There is a similar question on StackOverFlow but it was unhelpful and it wasn't answered. I have been working on a project and I currently am receiving this error.
Error: Cannot find module 'update-notifier'

If I type any command that includes npm it returns the same error, I can't install anything.
I have tried to uninstall/re-install NodeJS with homebrew but nothing changed from trying that.
