I am trying to npm install vue-mapbox mapbox-gl, and I'm getting a dependency tree error.
I'm running Nuxt.js SSR with Vuetify and haven't installed anything related to Mapbox prior to running this install and am getting this error.

What's the right way to go about fixing this upstream dependency conflict?
It looks like it's a problem with peer dependencies in the latest version of npm (v7) which is still a beta version.
Try with npm install --legacy-peer-deps. For detailed information check the blog post npm v7 Series - Beta Release! And: SemVer-Major Changes in npm v7.
Use --legacy-peer-deps after npm install. For example, if you want to install Radium, use:
npm install --legacy-peer-deps --save radium
There are two ways:
use npm install --legacy-peer-deps to install, and if this doesn't work use
the force method. Add --force next to npm install: npm install --force
You can follow these commands
First type:
npm config set legacy-peer-deps true
Then type:
npx create-react-app my-app
Your dependency mexample requires mmapbox-gl v1.13.0 and mvue-mapbox requires mmapbox-gl v0.53.0.
NPM doesn't know which version to install, so it gives a warning. You can bypass the errors using -- force or --legacy-peer-deps, but you are ignoring an error, and making unexpected results.
Production Options:
Probably one of your packages is outdated. Upgrading packages and fixing upgrade errors might fix the dependency conflict.
Overriding a dependency manually to avoid the warning and error. You are setting the version to a specific one that you know that works. Usually the newer version.
Example solution with override. Your package.json file will look like this:
{
"name": "my-app",
"version": "0.1.0",
"private": true,
"dependencies": {
"mexample": "^1.2.0",
"vue-mapbox": "*"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"overrides": {
"mmapbox-gl": "1.13.0"
}
}
The last option is bypassing using either:
--legacy-peer-deps completely ignores all peerDependencies using the newest version without pinning on file package-lock.json
--force forces the use of the newest, pinning all the versions on package-lock.json
Extra: You shouldn't use "*" as a version, because it might update major and break dependencies.
Until npm version 7.19.1, it still had the same issue. After upgrading to version 7.20.3, use command npm install -g npm#latest and npm audit fix. All packages will be fixed without error.
I tried multiple ways, but nothing was working for me. At last I tried this and it worked:
npm config set legacy-peer-deps true
Run this in the project folder and then try to install any package. It might work for you as well.
To solve it, fix the upstream dependency conflict installing NPM packages error
Method 1. Just use --legacy-peer-deps after npm install.
For example, if you want to install Axios, use
npm install --legacy-peer-deps --save axios.
Method 2. Updating npm and 'audit fix'
npm I -g npm#latest
npm audit fix --force
Method 3. Using --force to install packages
npm install axios --force
I was stuck on this issue for long which also makes error from other commands which calls for some install commands that was breaking.
The only solution that works (maybe suppresses the error) is
npm config set legacy-peer-deps true
This will set the configuration of legacy-peer-deps to true
To resolve npm dependencies and conflicts with npm packages, use npm-check-updates.
Almost all answers here suggest using force or legacy-peer-deps. Though this will technically work, please note that this is not recommended by NPM if you can avoid it anymore (source). Some folks may not have a choice, but I was able to resolve my dependency conflicts by deleting node-modules and package-lock.json then manually updating packages to their latest version one at a time until it stopped complaining (packages mentioned in the error messages after running npm i. Not a great or clean solution, but at least my packages are up-to-date and I'm not ignoring errors or using legacy solutions.
A lot of upvotes for using --legacy-peer-deps, but if --force works, I would recommend using that since it still pins many dependency versions while --legacy-peer-deps ignores peer dependencies entirely. See the example below:
npm: When to use --force and --legacy-peer-deps
I started getting this error on Azure DevOps a few days ago. I initially thought it was a glitch on the Azure side, but since it continued, we started looking into it a bit more.
It turns out the agent we are using, windows-2022, was updated a few days ago:
Updating readme file for win22 version 20220607.3 (#5713)
Node and NPM now match the latest Node.js LTS version: 16.15.1 (includes npm 8.11.0)
Downloads
You can view all agents-included software on Microsoft-hosted agents, Software.
After reading on Microsoft Visual Studio Developer Community, they recommend downgrading Node.js using Node.js Tool Installer task like this:
- task: NodeTool#0
inputs:
versionSpec: '16.14.2'
Node.js Tool Installer task
npm install fails in Azure DevOps Hosted Agent
However, we decided that we do not want to downgrade Node.js, so the first step was matching Node.js locally with LTS version 16.15.1 and npm 8.11.0.
When running npm ci, we then got the same error locally.
We tried npm ci --force and we then got this error:
npm ci can only install packages when your package.json and
package-lock.json or npm-shrinkwrap.json are in sync. Please update
your lock file with npm install before continuing.
npm install gave the same error even after node_modules was manually removed, but npm install --force worked, and it generated a new package-lock.json file.
npm ci still failed with the same error, but running npm ci --force worked. We decided to update Azure DevOps .yml to include --force and checked in the new package-lock.json file. After doing this, everything worked like before and we could now update our packages one by one.
delete the package-lock.json file
modify the package.json file, updating the version as indicated by the peer dependency
Add a tilde or caret for allowing install latest version and resolving dependency issues, for example :
~1.0.2 means to install version 1.0.2 or the latest patch version such as 1.0.4.
^1.0.2 means to install version 1.0.2 or the latest minor or patch version such as 1.1.0.
run npm install or npm udpate
I resolved this by adding
steps:
- task: NodeTool#0
inputs:
versionSpec: '12.x'
Nothing here worked for me.
After struggling with this issue for so long, I found a solution that worked.
Apparently I had some packages installed globally.
Listed them with:
npm list -g --depth=0
Then removed the unwanted packages with:
npm uninstall -g <package-name>
Finally I got the problem fixed

When trying to install the npm packages using npm i command, I am getting the following exception:
I have tried reinstalling the Node.js package and setting the proxy to off using:
set HTTP_PROXY=
set HTTPS_PROXY=
The issue is still there. What I am doing wrong?
Update:
When I run the following command:
npm install --legacy-peer-deps
The following error is displayed:
This is not related to an HTTP proxy.
You have dependency conflict (incorrect and potentially broken dependency) as it says, so try to run the command with --force, or --legacy-peer-deps. If it doesn't take effect, the temporary solution is using prior versions of the Node.js (downgrading the Node.js version) as it causes this kind of errors to happen sometimes.
Update based on the OP's update:
As you see, it fires the following error:
No matching version found for #angular/http#^9.1.4.
Take a look at angular/http page. Note that the latest version for that deprecated package is 7.2.16 while you request an upper version (e.g., ^9.1.4)! So, try to check the project dependencies and follow the raised errors in order to solve the problem.
Try this command-
npm install --save --legacy-peer-deps
First to understand the problem. Here is what I have as error:
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: project-admin#11.0.0
npm ERR! Found: #angular/common#11.0.3
npm ERR! node_modules/#angular/common
npm ERR! #angular/common#"11.0.3" from the root project
npm ERR!
npm ERR! Could not resolve dependency:

npm ERR! node_modules/#agm/core
npm ERR! #agm/core#"3.0.0-beta.0" from the root project
First you should start to read the problem from the bottom to the top. Here #agm/core#3.0.0-beta.0 requires angular common 9.1.0 or 10.0.0. And the top message says that the angular common found is actually 11.0.3.
(If you want to understand dependencies little bit better, here is very simple site: How npm3 Works)
dependencies — these are the essential dependencies that you rely on and call in your project’s code
devDependencies — these are your development dependencies, for example, a prettier library for formatting code
peerDependencies — if you set a peer dependency in your package.json, you are telling the person who installs your package that they need that dependency with the specified version
optionalDependencies — these dependencies are optional and failing to install them will not break the installation process
bundledDependencies — it’s an array of packages that will come bundled with your package. This is useful when some 3rd party library is not on NPM, or you want to include some of your projects as modules
So what should be the solution then? The problem is about peer dependencies. The solution is to downgrade angular common or the solution is to use legacy dependencies logic for installing packages using --legacy-peer-deps. So --legacy-peer-deps does not try to install the peerDependencies automatically. Is this going to work for you? Probably, yes. But you should add specific instructions how to do that, or to make the use of --legacy-peer-deps automatic for future installation of the project packages with this code from one of the previous answers:
npm config set legacy-peer-deps true
In my case I installed the package and I tried to run ng serve, but because --legacy-peer-deps was used, there were dependency packages which were not installed. I had to install those manually (because I did not set the configuration from the code above). At the end installing about five packages manually, all with --legacy-peer-deps, I ended to a package that could not be installed and I did not try to continue, because my project was throwing warnings like crazy and there were a lot of packages for audit too. So my decision was not to use this package and to find an alternative.
Other solutions that I read about along the way:
downgrade Node.js to v14. This will downgrade npm. It might not be v14, but this was the version that was most widely downgraded to.
Some people use Yarn to force package installation - personally I don't understand how this works, because I haven't used Yarn.
downgrading Angular and the global Angular CLI version to version that will satisfy the requirement. In my case it is angular/common, and in the question it's angular/core, but both require downgrading the whole angular right (I am not sure about this here).
the package you install might have a higher version that doesn't require downgrading Angular. You might try to use the https://updatepackagejson.com/ to upgrade your packages to the latest, but this is in case your project is quite new.
In addition to using the --legacy-peer-deps command line option, this can also be set more permanently as a config option:
npm config set legacy-peer-deps true
Finally, I found the answer. Try this command -
npm install --save --legacy-peer-deps
Described here legacy-peer-deps
When using npm 7, this comes up a lot because peer dependencies issues are treated as errors in version 7 whereas they were generally only warnings in version 6. Usually using --legacy-peer-deps makes it work with npm 7.
When that doesn't work, an option is to downgrade to npm 6. Downgrading Node.js is not necessary (but not harmful either). The relevant dependency management code is in npm. Downgrading Node.js will often work coincidentally because doing so will often downgrade npm as well.
Another option that is less disruptive than downgrading npm is using npx to use the previous version of npm for just the install command: npx -p npm#6 npm install
And when all else fails, it's often worth a shot to remove the node_modules directory and package-lock.json, and then run npm install again. That regenerates node_modules and package-lock.json.
This happens for some packages after updating to npm 7.
Parameter --legacy-peer-deps can help:
npm i --legacy-peer-deps
Described here legacy-peer-deps
Causes npm to completely ignore peerDependencies when building a
package tree, as in npm versions 3 through 6.
If a package cannot be installed because of overly strict
peerDependencies that collide, it provides a way to move forward
resolving the situation.
...
You can set this option to true by default (not recommended by npm):
npm config set legacy-peer-deps true
Or just wait until these packages get up to date.
Just do two simple steps:
First, execute this in your terminal.
npm config set legacy-peer-deps true
Second, clear the cache:
npm cache clean --force
And finally, execute your command. This will work for sure.
The problem is related to a dependency conflict or broken dependency. You can proceed by accepting the incorrection of dependency by forcing an install.
Solution: Using command with --force.
Your command will be like npm install --force #your-npm-package.
Note: You can use yarn to install a dependency if it's available in to install with the yarn package manager.
NPM can be used to install and manage versions of dependencies in your projects.
I had it the same issue on React versions in relation with the npm version:
npm error found types/react#16.14.20
So it might be package-versions that need to be installed based on your package.json file.
It gives errors in the npm 7 version and cannot install Node.js modules.
If you will downgrade npm version to 6, those problems will become warnings and the problem will be resolved.
Try to prove this command: npm install -g npm#6
Check if version is already installed: npm --version
Remove and install node_modules package:
a) Remove rm -rf node_modules
b) Install: npm i
Try removing the node modules and package-lock.json file and run command npm install
or
Try npm cache clean --force
First I tried
npm install
It gave me error unable to resolve dependency tree and based on the help information from this command,
Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.
I tried this command:
npm install --legacy-peer-deps
And it solved my problem.
Try two options to resolve this issue:
Option 1: Delete folder node_modules folder and file package_lock.json after running:
npm cache clean --force after npm i --force
Option 2: run npm install --save --legacy-peer-deps
The fastest solution: npm install --legacy-peer-deps
Explanation:
In npm versions 3 through 6, peerDependencies were not automatically installed, and would raise a warning if an invalid version of the peer dependency was found in the tree. As of npm v7, peerDependencies are installed by default.
npm docs: peerDependencies
Your dependency contains some peerDependencies that conflict with the root project's dependency.
As it described in the npm ERR log.
Disclaimer: This assumes you're on npm v7
Note: If you follow the instructions of sibling commenters, it will create a user-scoped config that won't sync consistently across teammates / machines / buildbots.
Project-based legacy peer dependencies
You will probably want legacy-peer-deps tied to your project so it proliferates across machines / developers, and doesn't contaminate your other projects.
npm config set legacy-peer-deps true --location project
This will create a local file at .npmrc which you can commit to your repository:
legacy-peer-deps=true
Then afterwards, you can just run:
npm install
Then commit the updated lockfile.
Remember, location, location, location:
per-project configuration (/path/to/my/project/.npmrc, see more):
npm config set legacy-peer-deps true --location project
per-user configuration (defaults to $HOME/.npmrc, see more)
npm config set legacy-peer-deps true --location user
or, as the default location is user anyway:
npm config set legacy-peer-deps true
global configuration (defalts to $PREFIX/etc/npmrc, see more)
npm config set legacy-peer-deps true --location global
or, as --global infers --location global
npm config set legacy-peer-deps true --global
For some projects, fixing dependencies may be non-trivial
In my case, a critical dependency we have a legacy version of wants to pull in webpack v3 (!) - but that's a build dependency of that project's.
The best solution on a short term basis is to use legacy-peer-deps as a hold over.
If you are in a pinch, you could also consider forking the dependency and adjusting its peer dependencies accordingly - them point your project to the fork.
You can install the packages using two ways it is showing this error
ERESOLVE unable to resolve dependency tree
Install the package using npm install and having --legacy-peer-deps
npm install --save --legacy-peer-deps
This is a combination of two commands
a. Set legacy-peer-deps true in npm config
npm config set legacy-peer-deps true
b. Now install packages using npm install
npm install
The problem seems to be that gf-kautomata-pipeline-ui is using Angular 9, while #angular/http requires Angular 7. (#angular/http was deprecated and eventually removed, and all its functionality was moved into #angular/common instead.)
See: https://www.npmjs.com/package/#angular/http
If you're running Angular 9, then
delete #angular/http from your package.json (You don't need it in Angular 9)
Make sure you have #angular/common in your package.json.
Run npm i.
If you're running Angular 7, then open up your package.json and check to make sure all of your Angular packages are no higher than ^7.0.0. You may also need remove gf-kautomata-pipeline-ui, or contact the author of gf-kautomata-pipeline-ui and find out if the library is compatible with Angular 7.
This works for me:
npm install --save --legacy-peer-deps
In my case, I started getting the error (below) after upgrading npm from version 6 to 7.
npm ERR! code ERESOLVE npm ERR! ERESOLVE unable to resolve dependency

...
npm ERR! Fix the upstream dependency conflict, or retry this command with --force, or --legacy-peer-deps to accept an incorrect (and potentially broken) dependency resolution.
In my case compiling with either --legacy-peer-deps or --force flags resulted in a useless bundle.
So I tried deleting the node_modules, package-lock.json, and bundle using yarn install. This generated a yarn.lock file and created package-lock.json that worked fine in subsequent npm runs.
P.S.: I am using the temporary workaround until npm 7 works fine with my project: after that, I will delete yarn.lock, package-lock.json and folder node_modules, and recompile with npm
rm -rf node_modules
rm package-lock.json
yarn install
# Generates a yarn.lock file and a new package-lock.json
# Continue with npm

If you have node_modules folder and package-lock.json file in your root directory then remove those:

Create .env file in the root directory and paste below code:

I have faced this issue many times. At last I found a solution:
npm install react-native-paper --legacy-peer-deps
Use
npm install --legacy-peer-deps
This worked for me.
For this case, I was having the issue
ERESOLVE unable to resolve dependency tree
in an Angular 13 project that used some packages from a private npm feed in Azure DevOps.
To access this repository, I created an .npmrc file. Because of this, the npm install command would search all packages in my private repository and not in npm feed any more. The unable to resolve the dependency tree error happened because the npm install command could not find many of the packages that were hosted in the npm feed and not my private feed.
I found this amazing answer on how to scope packages.
Based on this, I made some changes:
In my library Package.json, update the name to have a scope name #mylib
"name": "#myLib/command-queue",
Build and publish this package to my private feed
In my client app (the one that uses this package), update the .npmrc file to use my private feed for packages in this scope only
#myLib:registry=https://pkgs.dev.azure.com/...
always-auth=true
Now, whenever I run the command npm install, if the package has the scope #myLib, it will look for it in my private feed, and use the npm feed for all other cases (i.e., #angular/...)
This is an example of my client app Package.json file:
"#angular/platform-browser-dynamic": "~13.3.0",
"#angular/router": "~13.3.0", <-- this comes from npm
"#myLib/jcg-command-queue": "^2.2.0", <-- This comes from my private feed
Also, with this change, there isn't any need to add --legacy-peer-deps to the npm install command any more.
We had the same issue resulting in the error bellow:
npm ERR! code ERESOLVE npm

We use npm ci for clean install in Azure-Pipelines.
The issue was very often, that package.json and package-lock.json were not in sync anymore.
Solution to it was to execute npm install local and push the new package-lock.json.
As and additional hint we added a new task in the pipeline for additional informations if the the job fails.
- task: Npm#1
displayName: npm install
inputs:
command: custom
customCommand: ci
customRegistry: useNpmrc
# ##vso[task.logissue type=error] writes the text to the summary page (error-log).
- bash: echo "##vso[task.logissue type=error] If 'npm install' fails with 'ERESOLVE could not resolve', 'package.json' and 'package-lock.json' (needed for 'npm ci') may be out of sync. Run 'npm install' locally and push the new package-lock.json."
condition: failed() # Only execute on fail
displayName: npm install failed hint
Resetting package-lock.json works good for me all the time:
git checkout -- package-lock.json
Details:
Been experiencing this a lot when updating all packages of the legacy project - I highly don't recommend using npm audit fix nor npm i --force. Deleting the package-lock.json didn't work for me all the time as well. Rollback to the working version of package.json + package-lock.json and add packages turned out to be the safest and fastest variant for me.
Just in case, I did have similar behavior, when I tried either npm upgrade my current Angular 11.x based boilerplate from previous ng new or create new ng new abc based on Angular 12.x. I simply forgot to upgrade Angular CLI. So this npm install -g #angular/cli#latest solved my errors during ng new abc.
In my case I was having trouble with a #babel/core dependency, but I didn't want to use --force, because I was not sure about the consequences, so I went to https://www.npmjs.com/, looked for the package and replaced my old version with the newest one. That did the work.
This is an issue of Node.js version. Some latest versions of Node.js could show errors like these.

Removed node_modules several times and tried to reinstall. Can't understand what's the reason that causes this and how to fix it.
metzelder's answer helped me fix the issue. however if you run the command npm cache clean, it will give you a message
As of npm#5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid
So, as of npm5 you can do by adding a --force flag to the command.
So the command is:
npm cache clean --force
npm rebuild
it has solved my problem
Try removing package-lock.json and the node_modules folder:
rm package-lock.json
rm -r node_modules
I had the same issue with npm install.
After a lot of search, I found out that removing your .npmrc file or its content (found at %USERPROFILE%/.npmrc), will solve this issue. This worked for me.
npm uninstall
npm cache clean --force
I tried these two methods but they didn't work. After, I deleted the node_modules directory and ran npm install again, it still didn't work. Lastly, I deleted package-lock.json and created a new package-lock.json file using
npm install
I have overcome this issue by doing following:
Delete all the content of the npm dependencies. You can find the default install location according to this thread:
https://stackoverflow.com/a/5926706/1850297
Before you run npm install command, I suggest to run npm cache clean --force
npm rebuild will work for sure
In my case, update to the newest version:
npm install -g npm
I deleted
node_modules
and then reinstalled by
npm install
It worked for me
I have also faced the same problem and this is how i resolved it.
First of all you need to make sure that your node and npm versions are up to date. if not please upgrade your node and npm packages to latest versions.
nvm install 12.18.3 // update node version through node version manager
npm install npm // update your npm version to latest
Delete your node_modules folder and package-lock.json file.
Force clean the entire NPM cache by using following comand.
npm cache clean --force
Re-Install all the dependencies.
npm install
If above step didn't resolve your problem, try to re-install your dependencies after executing following command.
npm rebuild
This issue can also happen if you're trying to install a package that doesn't exist or if you're trying to install a version that doesn't exist.
npm cache clean returns below message
As of npm#5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead. On the other hand, if you're debugging an issue with the installer, you can use npm install --cache /tmp/empty-cache to use a temporary cache instead of nuking the actual one.
If you run npm cache verify, as specified above, then it actually runs cache verification and garbage collection which fixes the problem.

Happened in docker (node:15-buster) for me.
Remember to use WORKDIR /<folder> so that it doesn't conflict with original npm libraries installed.
The folder can be anything but system folders, so that includes using /.
In case none of these answer work for you, it may be because the terminal you're using isn't the right one/ your node_modules is used by another part of your computer.
In my case I kept juggling between this error (maximum call stack size exceeded) and the access error event when I did a sudo npm i.
The fix was to close my IDE (which was WebStorm), run npm i in a basic terminal, and that was it.
I'm not a Windows user, so if you are, try to check Rene Knop comment.
For Unix/OSX users, I've removed the root .npmrc file ~/.npmrc.
Before you're going to try it, please,
check if there is nothing necessary over there
you can use this command to bring all content into your terminal: cat ~/.npmrc .
If you have got something like:
cat: /Users/$USER/.npmrc: No such file or directory
to save a copy:
cp ~/.npmrc ~/.npmrc_copy
Now, try to remove it (Works for bash users: Unix / Ubuntu / OSX ...):
rm -f ~/.npmrc
This worked for me.
Hope this will be helpful for others.
I also had the same problem. I had tried the previous solutions, but the solution for me was much simpler. I only had to remove the space in the directory and then run npm i again
Thanks to: https://github.com/nodejs/node-gyp/issues/809#issuecomment-155019383 for pointing this out.
In my case I had a custom .npmrc file that included an auth token for authenticating with a private npm registry.
The token had expired, which helpfully returned code E401: Incorrect or missing password locally, but ERR! Maximum call stack size exceeded from the CI build.
You uninstall npm package and force clean the cache and close terminal and reinstall whichever package be.
$sudo npm uninstall <package - name>
$sudo npm cache clean --force
Then restart terminal and check
Still not working upgrade both npm and node to the latest version
Today we encountered this error when running an npm prune even after running an npm cache clean --force.
Versions:
node 13.8.0
npm 6.13.6
Deleting the package-lock.json worked for this case as well. Thank you all!
In general, once a module has been installed, it's much more convenient to use npm ci instead of npm install. Please check out this SO answer for the advantages of the former with respect to the later in a production environment.
So please just run
npm ci
All dependencies will be updated, and the problem will disappear. Or it will error in the case there's some grave de-synchronization between one and the other.
Most of the times, this issue occurs if you are using the system provided by the organization you work for and it's vpn restricts the use of this command.
In this case, you may try to disconnect from organization vpn and then execute this command.
I tried everything to fix this issue on my Mac. I think the issue started when I had already downloaded npm from Node.js and then reinstalled it with Homebrew while following along with a Team Treehouse video.
Here's what I tried:
From https://docs.npmjs.com/misc/removing-npm
sudo npm uninstall npm -g
sudo make uninstall
sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*
From How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)
sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}
Here's what worked:
In the end, the only thing that worked for me was to clone down the npm-reinstall repo from GitHub that completely removed everything related to npm on my Mac.
https://github.com/brock/node-reinstall
I then had to reinstall node and npm from Node.js.
I tried everything to fix this issue on my windows 7 machine like
Reinstalling and rebuilding npm
At last, I fixed this small configuration setting issue by wasting my entire day.
How I resolved this issue
Removing my project specific configurations in global .npmrc
at location like drive:/Windows/Users/../.npmrc
I solved it 100% I had this problem with gulp version: 3.5.6.
You should clean the package-lock.js and then run npm install and It worked form
Our company dev environment uses Artifactory as the default registry for our NPM dependencies, and when running npm install it was defaulting to this, which did not work... so manually specifying the main npm registry via npm install --registry https://registry.npmjs.org fixed this issue for me...
I was facing the same error, I was trying to install jest into to one of the packages in a monorepo project.
If you are using Yarn + Learna to package a monorepo project, you will have to navigate to the package.json inside the target package and then run npm install or npm install <package name>.
I don't know why, but I ran npm install with sudo and it worked.
sudo npm install
I had this problem and it was due to an upgrade of my git executable. I rolled back to Git-2.21.0.rc1.windows.1-64-bit and added this to my environment path and it fixed my issue.
The one thing that finally worked for me on Mac was upgrading from node 8.12 to 10.x using NVM.
I uninstalled all other versions of Node with NVM, then installed 10.x, then ran nvm alias default node, which tells NVM to always default to the latest available node version on a shell.
After that, my live reloading issue went away!
Switching to yarn solved the issue for me.
I'm having an issue with the create-react-app command. I've followed the instructions twice, tried other solutions such as adding
"resolutions": {
"ajv": "6.8.1"
}
to the package.json file then uninstalling and reinstalling ajv#6.8.1. I've tried using yarn but ended up just starting it all over to use npm, just to get the same error. Most answers I am finding are a year or more old. any help is Appreciated!
Here is the error message..
npm start
scilenceapp#0.1.0 start C:\Users\chris\OneDrive\Documents\coding stuff\SciLence\ScilenceApp\scilenceapp
react-scripts start
There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.
The react-scripts package provided by Create React App requires a dependency:
"webpack": "4.42.0"
Don't try to install it manually: your package manager does it automatically.
However, a different version of webpack was detected higher up in the tree:
C:\Users\chris\node_modules\webpack (version: 4.41.2)
Manually installing incompatible versions is known to cause hard-to-debug issues.
If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That will permanently disable this message but you might encounter other issues.
To fix the dependency tree, try following the steps below in the exact order:
Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
Delete node_modules in your project folder.
Remove "webpack" from dependencies and/or devDependencies in the package.json file in your project folder.
Run npm install or yarn, depending on the package manager you use.
In most cases, this should be enough to fix the problem.
If this has not helped, there are a few other things you can try:
If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
This may help because npm has known issues with package hoisting which may get resolved in future versions.
Check if C:\Users\chris\node_modules\webpack is outside your project directory.
For example, you might have accidentally installed something in your home folder.
Try running npm ls webpack in your project folder.
This will tell you which other package (apart from the expected react-scripts) installed webpack.
If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That would permanently disable this preflight check in case you want to proceed anyway.
P.S. We know this message is long but please read the steps above :-) We hope you find them helpful!

try also npm cache clean --force
While staring React app using npm start this error occurred...
I tried below things:
remove node_module package and reinstall
use yarn instead npm
3.update fsevent library using npm
still getting this error
Note: If we create react app fresh/new yarn start will work, but we close the terminal and restart using same thing below error occurred
/Users/nannam/test-app-2/node_modules/chokidar/lib/fsevents-handler.js:28

npm audit fix --force
It worked in my case
below steps solved issue :
step 1 : removing node_module and yarn.lock
step 2 : yarn install
step 3 : yarn start
This is a well-documented issue on the react GitHub repo with a couple of options to try.
I solved my error by re-installing the fsevents npm i fsevents, which worked
I solved with
sudo npm i fsevents --unsafe-perm
The #not-a-file gave will work only you can install the fsevents successfully。
but when I do that, I receive an error with this:
Error: EACCES: permission denied, mkdir '/Users/**/node_modules/jest-haste-map/node_modules/fsents/.node-gyp'
So ,I suggest you avoid this by use something like this:
sudo npm i fsevents --unsafe-perm=true --allow-root
And I also find this error may due to node version, when I use node 12,I can not install fsevents successfully , so I use nvm to modify my node version to v11.15.0
👍 Solved it using Yarn's selective dependency resolutions
"resolutions": {
"chokidar": "^3.3.1"
},
as some packages in my dependencies are still on older chokidar versions < 3
I also had the same issue though am using MacOS the issue is kind of bug. I solved this issue by repeatedly running the commands,
sudo npm cache clean --force
sudo npm uninstall
sudo npm install
One time it did not worked but when I repeatedly cleaned the cache and after uninstalling npm, reinstalled npm, the error went off. Am using Angular 8 and this issue is common
Do these simple steps. Run the following
rm -rf node_modules/ package-lock.json
and then
npm i
This worked for me.
For me, downgrading node to v11.15.0 solved the error.
remove node_module and package-lock.json and use yarn instead of npm. This saved me hours.
I deleted the node modules package and reinstalled the node and then executed the node js commands. it worked fine for me.
I FINALLY resolved the issue. The fsevent error occurred right after I installed bootstrap from my VS code terminal. I ended up using the react-bootstrap-github stylesheet code instead and put it in my index.html!
I solved changed my "package.json" using this react-scripts": "2.1.8
I had the same issue. I run the following command and it is working fine now, without using Yarn.
"npm audit fix"
I just solved this issue in node v11.15.0 my solution was: with my "react-scripts" version in "3.0.1" I just update it to "2.1.8" and run npm install after. You can use this version or search for one that works for you. Another option is updating nodejs to the latest version, then remove modules and run npm install.
Currently, we did not found any permanent resolve, but you just create that app again or use yarn package manager to install all modules again in your react app then run yarn start. that's how I solve my issue in react app.
I was able to get it working after running:
$sudo npm install npm#latest -g
I had this issue using the ng serve command. I tried all of the above combinations and none of them seemed to fix this issue permanently. A simple quick fix / get around for me was to close and reopen the terminal.
I had this error TypeError: fsevents is not a constructor and tried all answers (remove node_modules, uninstalling/installing fsevents, sudo npm cache clean --force, sudo npm install/uninstall) listed; but nothing resolved it. For some reason, fsevents is breaking for node version >v10.x.
Regenerating lockfile resolved this issue
npm i --package-lock-only
Run this command
npm install latest-version
Run:
npm audit fix --force
Then, try again.
This often happens due to the continuous update to react and npm-packages.
Try to remove your node_modules
npm uninstall
delete your yarn.lock
this will save tons of time and if you are using npm instead if yarn
always updated.
run yarn install
After trying "npm audit fix --force" did not work , I tried:
Removing node_modules folder
npm i
worked for me
I've got a maven project, within which is JavaScript project cloned as a git sub-module. So the directory structure looks like mavenapp/src/main/javascript/[npm project files]
Inside my package.json, the test looks like this:
"test": "react-scripts test --env=jsdom",
but when I try to run npm test, it says
'react-scripts' is not recognized as an internal or external command,
Interestingly, when I clone the javascript project independently I don't get this error. I've tried re-running npm install.
NPM version: 5.5.1
Node.js version: 9.3.0
It is an error about react-scripts file missing in your node_modules/ directory at the time of installation.
Check your react-script dependency is avaliable or not in package.json.
If not available then add it manually via:
npm install react-scripts --save
If react-scripts is present in package.json, then just type this command
npm install
If react-scripts is not present in package.json, then you probably haven't installed it. To do that, run:
npm install react-scripts --save
Try:
rm -rf node_modules && npm install
Wiping node_modules first, often tends to fix a lot of weird, package related issues like that in Node.
Running these commands worked for me:
npm cache clean --force
npm rebuild
npm install
In my situation, some problems happened with my node package. So I run npm audit fix and it fixed all problems
2023 answer: simply remove node_modules folder and run
npm install
or:
yarn
(depends on you're using npm or yarn)
it worked for me!
no need to do more!!!
It waste a lot of my time until I discover this, I got headache...
Faced the same problem, although I am using yarn.
The following worked for me:
yarn install
yarn start
To avoid this issue to re-occur or you face this issue whenever anyone downloads your project fresh.
It's better to add this in dev dependencies using this command:
npm install react-scripts --save-dev
It will get added like this.
"devDependencies": {
"react-scripts": "^4.0.3"
}
Do Commit and push your code.
Running the npm update command solved my problem.
To rectify this issue follow the following steps
run npm install
then run npm start
This worked fine for me
For Portable apps change
package.json
as follows
"scripts": {
"start": "node node_modules/react-scripts/bin/react-scripts start",
"build": "node node_modules/react-scripts/bin/react-scripts build",
"test": "node node_modules/react-scripts/bin/react-scripts test",
"eject": "node node_modules/react-scripts/bin/react-scripts eject"
}
react-scripts should be listed as a dependency when you run npx create-react-app your-app, but for some reason, it gets this error. I will list some steps that I followed that may help you fix this error:
First, check at your React package.json if there is react-scripts or not:
for example, you should see:
"dependencies": {
...
"react-scripts": "4.0.3",
...
},
If it's already there, now try to re-install your dependencies with npm i
If you still get the same error, try to remove your node_modules with rm -rf node_modules/, then re-install your dependencies with npm i
BUT if the package react-scripts wasn't in your package.json file, you should install it by your package manager like:
npm i react-scripts
then try to start your app with npm start
This is how I fix it
Check and Update the path variable (See below on how to update the path variable)
Delete node_modules and package-lock.json
run npm install
run npm run start
if this didn't work, try to install the nodejs and run repair
or clean npm cache npm cache clean --force
To update the path variable
press windows key
Search for Edit the system environmental variable
Click on Environment Variables...
on System variable bottom section ( there will be two section )
Select Path variable name
Click Edit..
Check if there is C:\Program Files\nodejs on the list, if not add this
I uninstalled my Node.js and showed hidden files.
Then, I went to C:\Users\yourpcname\AppData\Roaming\ and deleted the npm and npm-cache folders.
Finally, I installed a new version of Node.js.
I faced the same issue. I solved it using npm audit fix --force
I had the same issue. I did everything which suggested here. but nothing worked. I had installed react-scripts in my node_modules also used cache but all in vain. then I just npx create-react-app and moved all my code into this new folder and all worked.
npx create-react-app myapp
As for me i managed to fix this issue by install this :
npm audit fix --force
and it work after that.
This is not recommended, so plz don't down arrow, but for troubleshooting..
react-scripts is not recognized as an internal or external command is related to npm.
I would update all of my dependencies in my package.json files to the latest versions in both the main directory and client directory if applicable.
You can do this by using an asterisk "*" instead of specifying a specific version number in your package.json files for your dependencies.
For Example:
"dependencies": {
"body-parser": "*",
"express": "*",
"mongoose": "*",
"react": "*",
"react-dom": "*",
"react-final-form": "*",
"react-final-form-listeners": "*",
"react-mapbox-gl": "*",
"react-redux": "*",
"react-responsive-modal": "*",
}
I would then make sure any package-lock.json were deleted and then run npm install and yarn install in both the main directory and the client directory as well if applicable.
You should then be able to run a yarn build and then use yarn start to run the application.
Use git bash or windows cmd with admin rights to run npm install while fixing this issue, running these commands inside the editor's terminals doesn't help.
first run:
npm ci
then:
npm start
In my case, the problem had to do with not having enough file permissions for some files the react-scripts package installation was going to write to. What solved it was running git bash as an administrator and then running npm install --save react-scripts again.
I have tried many of the solutions to this problem found on line, but in my case nothing worked except for reinstalling NVM for Windows (which I am using to manage multiple Node versions). In the installer, it detects installed Node versions and asks the user if they wish for NVM to control them. I said yes and NVM fixed all PATH issues. As a result, things worked as before. This issue may have multiple causes, but corrupted PATH is definitely one of them and (re)installing NVM fixes PATH.
This is rather old question but this might be of some help for future reference. Delete node_modules folder and run npm install again. Worked for me.
In my case , I edited my files on Linux where I had node v14.0.5 installed, when I rebooted to Windows where I had node v14.0.3 I got the same error. So I updated the node version on windows and all went fine for me.
had similar issue.. i used yarn to fix it.
i noticed that react-scripts was not found in my node modules so i decided to download it with npm but i seem to be failing too. so i tried yarn ( yarn add react-scripts) and that solved the nightmare! Hope this work for you as well. Happy debuging folks.
For me, I just re-installed the react-scripts instead of react-scripts --save.
Started getting this error in Azure DevOps yesterday out of nowhere when running npm run build:
'react-scripts' is not recognized as an internal or external command, operable program or batch file.
However when looking at npm ci that completed it was full of errors like:
FetchError: Invalid response body while trying to fetch

When commenting out the cache everything started working again:
npm_config_cache: $(Pipeline.Workspace)/.npm

inputs:

restoreKeys: |

The weird thing is that it has worked for over a year up until yesterday (2021-12-02) and we use the exact same code for caching as Microsoft has documented.
https://learn.microsoft.com/en-us/azure/devops/pipelines/release/caching?view=azure-devops#nodejsnpm
Noting Degraded or Unhealthy on Azure DevOps Status
https://status.dev.azure.com/
I had the same problem and I tried the above thing, but that did not work some how. So,
I just typed yarn. And it went.
When I make a new project using React, to install the React modules I have to run "npm install" (PowerShell) from within the new projects ClientApp folder (e.g. "C:\Users\Chris\source\repos\HelloWorld2\HelloWorld2\ClientApp"). The .NET core WebApp with React needs to have the React files installed in the correct location for React commands to work properly.
This worked for me:
Go to the project folder in CLI and type npm install.Go for a similar command if
using yarn etc.
Then type npm start if you are using Npm. Go for a similar command if using yarn
etc.
The file starts working
