I'm trying to create a web application using React JS that has a push-to-talk (PTT) feature on it.
One of the technologies that we will use is Mumble.
The demo https://voice.johni0702.de/?address=voice.johni0702.de&port=443/demo on this https://github.com/Johni0702/mumble-web repository is working fine.
I tried to run the repository on my local computer but got some different errors.
Installation Errors
I cloned and tried to install all of the libraries on the root folder of the repository using the npm install command on my local computer with Windows OS and Node JS v16 but I got this error below.
verbose stack Error: command failed

Then I switched the Node JS version using the NVM from v16 to v14.
I tried to install all of the libraries on the repository using the npm install command again but then got another different error.

I tried to delete the "prepare": "rm -rf dist && npm run build", code (line 45) on the package.json file.
I didn't know whether deleting the code would have an impact on running the app later or not.
I also searched on the internet and found this answer https://stackoverflow.com/a/62744648/8339172 to clear the npm cache, regenerate the package-lock.json file, and delete the node_modules folder.
I did all of them then I ran the "npm install" command again.
This time, there was no error.
Runtime Errors
Continuing the previous section, I tried to run the root of the repository by running the npm run watch command.
I didn't know whether this was correct or not because I usually enter the npm start command to run a React JS locally.
I didn't see any port configured on the package.json file so I opened the localhost:8080 address on my browser.
Unfortunately, there was nothing there. The browser said This site can’t be reached. localhost refused to connect.
The App Folder
Continuing the previous section, I tried to run the index.html file on the app folder by double-clicking on the file.
It seemed that the app crashed because I saw there was an error on the browser console as seen in this screenshot below.
Here is the error message:
Uncaught SyntaxError: Cannot use import statement outside a module (at index.js:1:1)
Questions
I want to learn how to create the demo (https://voice.johni0702.de/?address=voice.johni0702.de&port=443/demo) on the repository https://github.com/Johni0702/mumble-web. My questions are:
Which one is the source code of the demo app? Is it from the root folder of the repository or the app folder?
Continuing the first question, how to install all of the required dependencies for the demo app locally?
Continuing the first and second questions, how to run the demo app locally?
Environment
OS: Windows 11
Node: 14.21.2, 16.18.0, and 18.13.0 (switchable)
Finally, I could run the app (root level) on my computer.
From the installation error section, we could see that this error verbose stack Error: mumble-web#0.5.1 prepare: `rm -rf dist && npm run build` happened when a Windows-based computer tried to run a Unix-based command. There is no rm command on the Windows computer.
So I tried to install the WSL on my Windows computer https://techcommunity.microsoft.com/t5/windows-11/how-to-install-the-linux-windows-subsystem-in-windows-11/td-p/2701207.
After strugling with the WSL installation, I could run the npm install command on the app and no error message appeared.
But then I didn't know how to run the app. Fortunately, we found another similar repository that has the start script here https://github.com/Theofilos-Chamalis/mumble-web. Using the npm install and npm start, I finally could run a mumble implementation the frontend app.
Note: the app from the https://github.com/Theofilos-Chamalis/mumble-web was not updated like the https://github.com/Johni0702/mumble-web one but I think that's another issue from this question.
I'm trying to learn react, so I have this sample code for the full-stack react voting app, and I am trying to get it to work but after running npm install followed by npm start I receive the following error when I run npm start can anyone help me with this issue:

Step 1: $ npm cache clean --force
Step 2: Delete node_modules by $ rm -rf node_modules (rmdir /S /Q node_modules in windows) folder or delete it manually by going into the directory and right-click > delete / move to trash. If you are not updating your packages you can delete the package-lock.json file too.
Step 3: npm install
To start again,
$ npm start
This worked for me. Hopes it works for you too.
PS: Still if it is there, kindly check the error it is displaying in red and act accordingly. This error is specific to node.js environment.
Cleaning Cache and Node_module are not enough.
Follow this steps:
npm cache clean --force
delete node_modules folder
delete package-lock.json file
npm install
It works for me like this.
I resolve this error running following code
npm cache clean
then delete node_modules directory from my project structure manually or with following command
rm -rf node_modules
After That install dependencies again using
npm install
first i ran:
npm run clean
(even though it came with errors)
Then i deleted the node_modules folder and ran
npm install
This seems to have solved the problem.
I was getting similar error messages on a 16.04 Ubuntu instance with DigitalOcean while running npm run build on an app made with create-react-app (link). I upgraded the instance from 512MB RAM to 1GB ($5/mo to $10/mo) and then the script was able to run.
I post this here to point out that you may get this error due to resource limitations, which I didn't really see explained elsewhere on issue pages and SO answers. And nothing I saw in the error logs pointed me in this direction.
Change access in node_modules directory
chmod -R a+rwx ./node_modules
This solution is for Windows users.
You can open the node.js installer and give the installer some time to compute space requirements and then click next and click remove. This will remove node.js from your computer and again reopen the installer and install it in this path - C:\Windows\System32
or
Cleaning Cache and Node_module will work.
Follow this steps:
npm cache clean --force
delete node_modules folder
delete package-lock.json file
npm install
Faced this exact problem,
for me it worked by deleting package-lock.json and re-running npm install
If that doesn't resolve it try
delete package-lock.json
npm cache clean --force
npm install
npm start
Delete node_modules and package-lock.json, and then run npm install. It worked perfectly here(run command below inside project root):
rm -rf node_modules && rm ./package-lock.json && npm install
I was getting this npm ERR! code ELIFECYCLE error while running a build. Clearing the cache and removing the package-lock.json files did not fix it.
In my case there was an Angular build running on a Docker image that was causing this. The root cause turned out to be running the build on Docker in MacOS, which runs the Docker inside a Linux VM, and has by default 2GB memory allocated.
Giving Docker more memory fixed this issue for me. Have to say, the error message could have been quite a bit more clear..
A helpful answer for me was Call retries were exceeded exception while ng build
workaround: Remove the lock file.
rm .\package-lock.json
source: https://github.com/mapbox/node-pre-gyp/issues/298 (floriantraber)
React Application: For me the issue was that after running npm install had some errors.
I've went with the recommendation npm audit fix. This operation broke my package.json and package-lock.json (changed version of packages and and structure of .json).
THE FIX WAS:
Delete node_modules
Run npm install
npm start
Hope this will be helpfull for someone.
npm install --unsafe-perm
worked for me. See https://docs.npmjs.com/. The --unsafe-perm parameter lets you run the scripts from the package instalation as root. The problem in my case was that some depandencies failed to install.
This solution fixed the error in Win10.
Please install globally npm install -g node-pre-gyp
i tried to solve this problem with this way
rm -rf node_modules && rm ./package-lock.json && npm install
But for me its not work.
I just restart my machine and its working perfectly.
Am Linux user ,Machine HP.
I recommend you update your node version to the latest node version recommended by your application or for short update your node version. I encountered this same problem using node version 11.1 but my application was recommending atleast version 10.x.x or 12.x.x
I tried all the suggested reply on this thread but non seemed to work for me untill only when i updated my node version to the recommended latest version .i.e. version 12.16.3 then my application ran.
I just wanted to do run npm run dist to apply some changes for SCSS files, but after hours of suffering, here's what worked for me:
npm cache clean --force
delete node_modules folder
delete package-lock.json file
sudo npm install npm#latest -g this will upgrade npm to latest version
npm audit fix --force
npm upgrade --force
npm install
After these I could finally compile SCSS files successfully with npm run dist.

Solution: fix yo' warnings!

See CRA issue #3657
(Ashamed to admit that it just happened to me; did not see it until a colleague pointed it out. Thanks Pascal!)
I'm using ubuntu 18.04 LTS release and I faced the same problem I tried to clean cache as above suggestions but it didn't work for me. However, I found another solution.
echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches
npm start
I run this command and it started to work
In my case, I actually ran into this error "code ELIFECYCLE" in a Jenkins job. I tried to clean npm cache but it didn't work and also checked the memory of the Jenkins build server which looks okay. Then, I found the compiling of the react project actually failed in Jenkins but not in my local or when manually running the build on the Jenkins build server, and Jenkins also mentioned "Treating warnings as errors because process.env.CI = true". It looks like the warnings in my project cause the error on Jenkins. Therefore, I changed CI to true in the Jenkins job for now. That actually fixed the build error of Jenkins before I cleared those warnings.
Try to reinstall the cli package globally. In my case, I was trying to test a Vue.js tutorial when I get the same error message. The other thing I did was run the vue command again but this time using webpack-simple and that is why I am not sure wich one solved the problem but now it is working.
The port is probably being used by another application, try listing and see if it's your application:
lsof -i:8080
You can kill the process of this port:
lsof -ti:8080 | xargs kill
I've been bothered by this issue for a long time. For me, the version of node was the problem.
My npm and node were 6.1.0 and 8.11.3, respectively. However, I didn't realize that I had updated my node accidentally to 12.*.*.
It then began to install GCX stuff whenever npm i, which was unnecessary before.
I downgraded my node to 8 and it worked!
Its weird but it works for me
Go to
control panel -->System and Security--> System --> Advanced System
Security--> Environment Variables
In Environment Variable popup you will edit the user variable PATH and add "C:\Windows\System32" value as semicolon separated to the existing value.
Not but not least restart the Machine.
I did follow steps, it works:
1.
npm cache clean --force
remove the package-lock.json file
restart my WebStorm
Usually killall node command fixes mine.
Resolved like this:
# chown -R <user>: node_modules
Make sure to use the latest npm version while installing packages using npm.
While installing JavaScript, mention the latest version of NodeJS. For example, while installing JavaScript using devtools, use the below code:
devtools i --javascript nodejs:10.15.1
This will download and install the mentioned NodeJS version. This worked for me.
I was issuing the npm start command with the folder of the project opened at Sublime Text. Closing ST and restarting the server did the work for me.
After copied my Angular project from my local computer to my Linux server, I tried to run the project using ng serve and it didn't work. Instead it opened a new file in an editor in the console.
Then I researched and came up with npm start. However, that also not working. Gives me the following error.

What could be the reason for this ? And any solution.?
You may have to install angular cli on your linux server if you want to run it this way.
npm install #angular/cli -g
However, you may want to build your project for production if you want to serve it. Build it locally and push the built 'dist' folder to your server:
npm run ng build -prod
Try this
npm install -g #angular/cli
Following something similar to this... http://stuart-85933.onmodulus.net/ and that exact one. Tried a bunch of things for an hour and I'm dying. Help please!

Modulus is currently working on adding compatibility for some of the newer Meteor releases i.e. Meteor 1.4. More information about this error can be found in the issues noted below. You can see updates on this issue here:meteor github issue, meteor build runtime, demeteorizer github issue
Edit: There is a workaround if you are still having trouble, but it is a little lengthy. This workaround should work for any new version of Meteor that comes out, even versions that aren't working with the Meteor runtime yet.
Make sure the app runs locally
Install any unresolved modules
i.e. if you get this message when running locally:
Unable to resolve some modules:
XYZ ...
If you notice problems related to these missing modules, consider running:
meteor npm install --save XYZ
Run demeteorizer
$ npm install demeteorizer -g
$ demeteorizer
Change directory to .demeteorized/bundle/programs/server/
$ cd .demeteorized/bundle/programs/server/
Run npm install in that directory
$ npm install
Edit the package.json in that directory after running 'npm install' and specify the correct node engine: i.e. node 4.4.7
Change directory to root of the bundle
$ cd ../../
Make sure you are in the root of 'bundle,' and then zip the contents
$ pwd
/exampleDirectory/yourProject/.demeteorized/bundle
Zip contents of bundle
$ zip -r -X myProject.zip ./
Move that zip to the root of your project directory (or a non hidden folder)
Go to your project dashboard at my.modulus.io
a. Stop your project
b. Change runtime to node.js in the
'administration' panel
c. Confirm you have MONGO_URL and ROOT_URL
