In my situation it helped:

  1. clean cache with
npm cache clean --force
  1. install the latest version of npm globally as admin:
npm install -g npm@latest --force
  1. clean cache with
npm cache clean --force
  1. Try to install your component once again.

I hope this fix your issue. If it does not help, try to switch of antivirus program for a while and repeat.

Hi there - reading this thread and I believe I am having the exact same issue as you. App has been functioning well, no changes to code, and then all of the sudden this error. Now any time I try to update the file (even a simple console log) I get this error.

What was your solution?
