I was trying to run this SVELT GitHub repo on local server:
https://github.com/fusioncharts/svelte-fusioncharts
I tried to launch it with "npm run dev" command. But I am seeing this error:
npm ERR! missing script: dev
I have tried to fix the issue by setting 'ignore-scripts' to false with this command:
npm config set ignore-scripts false
But it doesn't work.
How can I fix the issue?
npm ERR! missing script: dev means you are there isn't a script having dev. You are likely running on an incorrect directory.
Fusion charts seem to work with svelte codesandbox.
npm ERR! missing script: dev means it cannot find a script called dev inside package.json.
That makes sense!
It looks at the package.json inside the svelte-fusioncharts repo. In that file, there is a scripts property.
Notice how that property looks as follows:
"scripts": {
"build": "rollup -c",
"prepublishOnly": "npm run build"
}
It does not contain a dev script. That’s why it says there’s a missing script. Other commands will work, like npm run build or npm run prepublishOnly.
Md. Ehsanul Haque Kanan,
"scripts": {
"build": "cross-env NODE_ENV=production webpack",
"dev": "webpack-dev-server --content-base public" }
The above is the script from the examples folder in the repo: https://github.com/fusioncharts/svelte-fusioncharts/blob/develop/examples/package.json
You have missed out on the "dev" script in your package.json file.
Please check the "package.json" file in your project and just add the "dev" script as in the repo link and then retry.
Alright. I have fixed the issue. I just go inside examples folder. Then I run the following commands:
npm install
npm run dev
I had the same problem.
It is due to changes in script object in package.json by me. I had installed nodemon and to run the code, I changed the script lifecycle events start and dev in package.json to run the code via nodemon.
But even after installing nodemon, it was not reflecting in devDependencies, so I made manual entry in package.json with its version seeing from package-lock.json.
"devDependencies": {
"nodemon":"^2.0.15"
}
Making this arrangement, my code started as expected.
So, check your recent npm package installation and verify its reflection in devDependencies or dependencies in package.json.
I am learning NODE js and i have a server file that includes NODE_env as port configuration , the code works on a MAC but throws up an error on my windows. How do i solve this?
Have you tried installing it globally or include it in your project's or your library's optional dependencies?
if not, try this:
install globally:
npm install -g win-node-env
Or you may include it in your project's or your library's optional dependencies:
npm install --save-optional win-node-env
refer below link for more information
npmjs win-node-env
If you run into this problem in 2021, install cross-env as a dev dependency by running npm i -D cross-env.
Then, modify your command in the package.json file thus:
cross-env NODE_ENV=development node my_script.js
Are you asking how to set NODE_ENV in windows? You can set it as a user or machine environment variable. You can also set it when you call the script in the command line:
NODE_ENV=development node my_script.js
I am trying to run react-d3-tree-demo following this README.md at https://github.com/bkrem/react-d3-tree-demo
After following the other steps, I got stuck on the second step of trying to run the app locally. The command line returns an error: "'BROWSER' is not recognized as an internal or external command, operable program or batch file," when I try to execute "npm run dev" in the react-d3-tree-demo directory that I cloned from the same repo.
The README.md page instructs to run "npm run dev" in both the react-d3-tree and react-d3-tree-demo directories. I actually got an error when I did that command in the react-d3-tree directory where the command line said the linebreak was incorrect, but I went into the eslintrc.js file and added "'linebreak-style': 0," in the module exports which resolved the error. I've tried turning off my Avast antivirus software which was suggested on another page. Nothing has worked so far.
To reproduce my problem:
Demo:
Clone this repo: git clone https://github.com/bkrem/react-d3-tree-demo.git
cd react-d3-tree-demo
Run yarn or npm install OR run bash ./setup.sh and skip to Running locally
React-D3-Tree library:
Inside the react-d3-tree-demo directory, clone the library: git clone https://github.com/bkrem/react-d3-tree.git
Run yarn or npm install
Running locally:
Set up 2 terminal windows, one in the react-d3-tree-demo directory, the other in react-d3-tree-demo/react-d3-tree (i.e. the sub-directory into which we cloned the library itself)
Run yarn dev/npm run dev in each
Any changes made to the demo app or the library should now automatically rebuild the library and reload the app with the fresh build (via nodemon).
I expect the react app to open a page at localhost:8000 that looks like this: https://bkrem.github.io/react-d3-tree-demo/ however, I get a message from the command line that was detailed earlier. I'm not sure why they told me to clone react-d3-tree inside the demo, I'd appreciate any explanation of that also.
Do an npm install of cross-env in your cloned repo:
npm install --save cross-env
Then in your cloned repo, open up package.json and change dev to this:
"dev": "cross-env BROWSER=none yarn clean:lib && webpack --progress --colors --watch --env dev",
Basically adding this to the beginning of the command: cross-env BROWSER=none
BROWSER is an environment variable, and you can use the cross-env package to properly handle it.
Now try running npm run dev again, and it should work.
There are two fixes I found that work perfectly well
Install cross-env (npm package cross-env) npm install cross-env then you change your dev script to
"electron-dev": "concurrently \"cross-env BROWSER=none yarn start\" \"wait-on http://localhost:3000 && electron .\"",
Install concurrently and run this (on windows though)
"electron-dev": "concurrently \"SET BROWSER=none&&npm run start\" \"wait-on http://localhost:3000 && electron .\""
please note that you also have to install concurrently if not already installed
i success using cross-env, so try this one:
"dev": "concurrently -k "cross-env BROWSER=none npm start" "npm:electron"",
"electron": "wait-on http://localhost:3000 && electron ."
Try this: paste this BROWSER=none in your project's .env file then save and re-run the project. Because maybe this a path related issue.
So I have a package.json file which I used on a different computer to run javascript tests. Now I have moved to another computer, I have the node_modules folder, package.json, package-lock.json and yarn.lock. If I run npm install in the same folder where package.json is located, shouldn't jest also be installed? Since Jest is located in package.json. If I run jest from the terminal I get command not found
Probably because the node_modules/.bin of your project is not in your $PATH try adding it or run ./node_modules/.bin/jest
To use an npm package from anywhere you need to have it installed globally like this:
npm install -g jest
An other solloution would be to add a new script in the package.json like this:
scripts:{
"jest":"jest"
}
And the type npm run jest
You can also have a look at this question : How to use package installed locally in node_modules?
I am doing node.js server setup from https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens. I am new in node.js. I am installing npm install nodemon --save. But when I am run the server with this nodemon server.js.
In the terminal showing:
nodemon is not recognized as internal or external command, operable
program or batch file
node server.js command is working and started the server, But nodemon command is not working.
I am set up the node js server from https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens video.
I don't know why it is not working I have tried some command for the install nodemon.
npm install -g nodemon
npm install -g nodemon --save
npm install --save-dev nodemon
npm install -g nodemon#debug
npm install -g --force nodemon
I have seen one link I can´t install nodemon globally, "nodemon" not recognized, But I don't know how to set the path because of my project location in D drive.
I want to run nodemon server.js. How can this be done?
You need to install it globally
npm install -g nodemon
# or if using yarn
yarn global add nodemon
And then it will be available on the path (I see now that you have tried this and it didn't work, your path may be messed up)
If you want to use the locally installed version, rather than installing globally then you can create a script in your package.json
"scripts": {
"serve": "nodemon server.js"
},
and then use
npm run serve
optionally if using yarn
# without adding serve in package.json
yarn run nodemon server.js
# with serve script in package.json
yarn run serve
npm will then look in your local node_modules folder before looking for the command in your global modules
Install nodemon globally:
C:\>npm install -g nodemon
Get prefix:
C:\>npm config get prefix
You will get output like following in your console:
C:\Users\Family\.node_modules_global
Copy it.
Set Path.
Go to Advance System Settings → Environment Variable → Click New (Under User Variables) → Pop up form will be displayed → Pass the following values:
variable name = path,
variable value = Copy output from your console
Now Run Nodemon:
C:\>nodemon .
No need to install nodemon globally. Just run this npx nodemon <scriptname.js>. That's it.
First, write npm install --save nodemon
then in package.json write the followings
"scripts": {
"server": "nodemon server.js"
},
then write
npm run server
I was facing the same issue. I had installed nodemon as a dev-dependency and when I tried to start the server it gave the message that
nodemon is not recognized as internal or external command, operable
program or batch file
Then I installed it globally and tried to start the server and it worked!
npm install -g nodemon
To use nodemon you must install it globally.
For Windows
npm i -g nodemon
For Mac
sudo npm i -g nodemon
If you don't want to install it globally you can install it locally in your project folder by running command npm i nodemon . It will give error something like this if run locally:
nodemon : The term 'nodemon' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling
of the name, or if a path was included, verify that the path is
correct and try again.
To remove this error open package.json file and add
"scripts": {
"server": "nodemon server.js"
},
and after that just run command
npm run server
and your nodemon will start working properly.
This may come to late, But better to say somthing :)
If you don't want to install nodemon globbaly you can use npx, it installs the package at run-time and will behave as global package (keep in mind that it's just available at the moment and does not exist globally!).
So all you need is npx nodemon server.js.
npx can be used out of the box from npm#5.2.0 version and up.
I had the same error a few minutes ago and this is how I've solved it:
1. Install "nodemon" Globally
npm install nodemon -g
2. Then you need to add the npm path to the environment variables
To find the path do this in the terminal:
npm config get prefix
You'll get the output that looks like this: C:\Users\user\AppData\Roaming\npm
If you're not sure about how you can update environment variables on Windows, check this out: Here
3. Run the app again with "nodemon"
Before you run the app, create a new terminal to make sure that the terminal recognises the changes in the environment variables.
Then run:
ex:
nodemon server.js
Does it need to be installed globally? Do you need to be able to just run nodemon server.js ? If not, you could always just call it from your local project directory. Should be here:
node_modules/.bin/nodemon
This line solved my problem in CMD:
npm install --save-dev nodemon
I tried installing the nodemon globally but that doesn't worked for me.
whenever i try to run it always shows me the error:
nodemon : The term 'nodemon' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling
of the name, or if a path was included, verify that the path is
correct and try again.
2. I have found two solutions for this
solution 1:
What i have tried is to update the "scripts" in package.json file and there i have added
"server": "nodemon app.js"
above line of code and after that
npm run server
Soluton 2:
Press the Windows key.
Type "Path" in the search box and select "Edit the system environment variables"
Click on "Environment Variables" near the bottom.
In the "System Variables" section double click on the "Path" variable.
Click "New" on the right-hand side.
Copy and paste this into the box (replace [Username]):
C:\Users[Username]\AppData\Roaming\npm
restart your terminal and VSCode.
Then type nodemon app.js to run the nodemon
i applied solution 2 as we just need to run nodemon [filename.js]
I have fixed in this way
uninstall existing local nodemon
npm uninstall nodemon
install it again globally.
npm i -g nodemon
It is better to install nodemon globally instead as dev dependency to the project.
npm install -g nodemon
Official NPM CDN: Link
This package is used to monitor changes in the javascript files and re run the npm start so that it is easy to dev purposes.
Since node prefix is not in the PATH ENV variable , any of the globally installed modules are not getting recognized.
Please try this.
Open cmd prompt
npm config get prefix
append the resulting path to PATH env variable.
Now you should be able to run nodemon from any location.
try this link and follow it.fixing npm permissions
https://docs.npmjs.com/getting-started/fixing-npm-permissions#option-2-change-npms-default-directory-to-another-directory
You can run your node app by simply typing nodemon
It First run index.js
You can put your entry point in that file easily.
If you have not installed nodemon then you first you have to install it by
npm install -g nodemon
If you got any permission error then use
sudo npm install -g nodemon
You can check nodemon exists or not by
nodemon -v
For me setting the path variables was enough for the solution:
Step 1) Install nodemon globally using npm install -g nodemon
Step 2) Set the ENVIRONMENT VARIABLES, by adding npm path the PATH variable
1) Open Control Panel, search for environment variable
2) Click open the environment variable
3) Create new variable NPM set it with the path of npm as appears from the nodemon installation cmd output (as seen from nodemon installation screenshot):
4) Now add NPM variable to the PATH variables:
Step 3) Close the 'cmd' and open a fresh one and type nodemon --version
Now we have the nodemon ready to use :)
This issue is also possible if running scripts is disabled on the system. In order to enable it:
Open Windows PowerShell with Run as Administrator
Execute:
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
npm install -g nodemon
nodemon app
Just had the same problem after creating a new user profile on my development machine.
The problem was that I wasn't running the console (command prompt\powershell ISE) as admin.
Running as admin solved this problem for me.
Just install Globally
npm install -g nodemon
It worked for me on Windows 10.
nodemon app.js
The Set-ExecutionPolicy cmdlet's default execution policy is Restricted for Windows.
You can try installing nodemon by setting this policy to Unrestricted.
execute command : Set-ExecutionPolicy Unrestricted
and then try installing nodemon and execute command: nodemon -v
First you need to install nodemon globally by using this command:
"npm i -g nodemon" (for Windows) and "sudo npm i -g nodemon" (for Mac)
then run
"nodemon app.js"
Now you will be fine.
Run this command:
npm install nodemon -g
Now it will install the nodemon but the problem with my case is that it is installing nodemon somewhere else.I added Nodejs path from (ProgramFiles(x86)) but that did not worked so i found another solution.
Run above command
There will be a path shown during installation where nodemon is installed,then
[Kindly go to below link to see the path][1]
[1]: https://i.stack.imgur.com/ld2sU.png
Copy the path upto npm and set it to environment variable
Now try the below command,hopefully it will run
nodemon YourAppName.js
All above options are failed, I got the permanent solution for this.
Add below line in package.json under dependencies and run npm install. This will add nodemon package to node_modules and there you go, enjoy the coding.
"nodemon": "^1.17.*"
Try in your packge.json:
put "./node_modules/.bin/nodemon" instead of just "nodemon".
For me it works.
This help me with the same problem to start both nodemon and graphql servers
npm run dev
Step 1: $ npm install nodemon --> install nodemon on your project
Step 2: Add serve in script on package.json file as:
"scripts": {
"serve": "nodemon app.js" // you can change file name accordingly
}
Step 3: $ npm run serve
The following worked for me on windows 11.
Type npm install in the terminal. (Within the same directory as the project)
Then type npm run serve to run the application from the default browser.
Remove nodemon because it's a dev dependency and use node instead of it.
"scripts": {
"start": "node server.js"
},
This worked for me.
