Error: Cannot find module './lib/source-map-generator'

I opened an old project and getting this error suddenly… Any ideas how to fix?

@Hesesses Looks like your “node_modules” folder is incomplete. Try removing it and run npm install again.

If you can’t remove node_modules file, you can try this:

Install RimRaf:

npm install rimraf -g

And in the project folder delete the node_modules folder with:

rimraf node_modules

Then you can go and do npm install to get the fresh start.
