Error for "npm run build" at building module locally for sample app

[TimoPromann]

Hey guys,

"rm -rf dist && webpack --config webpack.config.js" is not working. The error states that "rm" is no valid command, but it should be. Full error message is:

22 verbose stack Error: command failed

My node version is: 15.0.1
npm: 7.0.6

I cloned the main directory (opentok-network-test-js) and ran "npm install". This took some time and yielded some warnings, but I got no errors. The warnings were:

Do you have any suggestions, what I am doing wrong?

I also tried to run "npm install opentok-network-test-js", open the opentok-network-test-js directory inside these node_modules and ran "npm install" in there. Similar results.

I am thankful for any help.

Hi @TimoPromann - thank's for writing in,

The issue is that rm isn't a valid command in the cmd - and since NPM likes to pipe windows shell commands directly through the windows cmd executable in c:\WINDOWS\System32, when it hits that rm -rf dist command it blows up. We're going to look into resolving this to make it more cross-OS friendly, but for the moment I'd recommend trying to do this in WSL, running this in PowerShell seems to encounter the same issue..

If that's not an option, you could replace this line with:

"build": "del dist /Q && webpack --config webpack.config.js",

that will leverage the cmd del command instead of the rm command

Hi @slorello89 - thank you for your comment!

The line you suggested worked for building the module in the main directory.

However, when trying to set up the sample app, "npm install", I got another error:

392 verbose stack Error: EPERM: operation not permitted, symlink '..\..' -> 'C:\Users\baj0712\app_dev\opentok-network-test-js\sample\node_modules\opentok-network-test-js'

405 verbose exit -4048

So it seems that within the node modules in the sample app, the folder "opentok-network-test-js" shall be reached. But this seems to fail.

Do you have another suggestion for me how to fix this?
