@wfgmiami Seems your have invalid permission, look on your first line in screenshot. Remove node_modules and try to install again.

@evilebottnawi I do not know why i get that permission denied message. I am able to install other packages like express for example. I removed node_modules, ran again but i got the same error.

@wfgmiami I see your work using root, it is not recommended (this can cause problems). But your can try to create minimum reproducible test repo, maybe it is allow to find your problem.

@evilebottnawi Thanks for your help. I did sudo apt-get install nodejs-legacy and after than I was able to npm install webpack.

Hey Everyone, I ran into the same issue and this is what it worked for me:

1. delete package-lock.json
2. npm cache clean --force
3. wait 1 min.
4. npm-install, this will create our new package-lock.json
   ( npm notice created a lockfile as package-lock.json )
