I have run npm install -g vercel and when I try to run vercel dev on cmd, it gave me this error, I have on windows 10 64bit, i already check my environment veraible, here is what i did
added C:\Windows\System32\ and C:\Windows\System32\cmd.exe to both of the top and bottom environment variable Path, anyone help?
I also tried
yarn cache clean
yarn
yarn start
What I also did is to reinstall node, again it doesn't work.

I couldn't figure the "right way" to do it for a whole day,
what I ended up doing is creating a file named 'cmd.exe'.
I ran this command in cmd:
type "C:\Windows\system32\cmd.exe" > cmd.exe

How to resolve EPERM: operation not permitted error in webpack command?

How to resolve EPERM: operation not permitted error in webpack command?
The following error message occurs when using webpack.
PS C:\Workspace\Mission> npm run dev
> webpack-demo#1.0.0 dev
> webpack --mode=development
[webpack-cli] [Error: EPERM: operation not permitted, open 'C:\Workspace\Mission\dist\px.bundle.js'] {
errno: -4048,
code: 'EPERM',
syscall: 'open',
path: 'C:\\Workspace\\Mission\\dist\\px.bundle.js'
}
Running the npm cache clean --force command works fine.
However, if I run the npm run dev command 3 or 4 times, the same error repeats again.
I gave the account admin rights, and I also gave full control to the folder. I tried running it in admin mode, but it didn't work.
How to fix this error?

So I was working with my React Native application and had to install react-native firebase storage for image storing. So I ran npm install #react-native-firebase/storage after installing it I re-run my server and after that, I am getting this error. I don't know why I am getting this error. Kindly help me out.

If anyone else is getting this error what you need to do is open your react native android folder in Android Studio and then build and run your application via Android Studio. It will successfully run the project after that close Android Studio and now again start your react native project.
Now you will get 0 errors.
Also, run npm outdated after running that try upgrading your outdated packages also as my storage version was 12.0 but auth and app of firebase was 11.2.

npm: command not found when executing commands in Electron app

I'm working on an electron app and within the app, I execute shell commands using child_process.exec. One of the commands I run is npm run start; this works perfectly in a dev environment but when I build the application for production all npm commands fail with showing the following error:
Error: Command failed: npm run start
/bin/sh: npm: command not found
at ChildProcess.exithandler (child_process.js:287)
at emitTwo (events.js:126)
at ChildProcess.emit (events.js:214)

at emitOne (events.js:116)
at Socket.emit (events.js:211)
at Pipe._handle.close [as _onclose] (net.js:554)
I tried running the application in debug mode by running the following command open MyApp.app/Contents/MacOS/MyApp and the npm commands run successfully with no errors.
What could be the issue?

The issue that the environment variable of $PATH is wrong inside the packaged app, it works in development because the application is launched from the terminal which gives it access to the $BASH profile.
To solve this problem I used this package fix-path. I installed the package and added the following snippet at the top of the file
if (process.env.NODE_ENV === 'production') {
const fixPath = require('fix-path');
fixPath();
}
I came to this answer after going through this issue on GitHub. Thanks to #Seblor
