I'm using node v6.11.2, npm v5.3.0 and angular/cli v1.2.7.

I'm suddenly receiving the following error message for a majority of my npm installs. Never seen it before...

mmeppiel@MC-LT-MMEPPIEL MINGW64 ~/Desktop/Angular Solutions/my-app (master)
$ npm install --save [email protected] font-awesome

Can anyone explain what's going on here? Things I've tried:

  • Running Git Bash as an administrator
  • Turning off my firewall and AntiVirus protections
  • Running npm cache clean
  • Manually deleting the contest of AppData\Roaming\npm-cache
  • Uninstalling node via the Control Panel and reinstalling
  • Gave Everyone full permissions to C:\Program Files\nodejs
  • Reinstalled the CLI
  • Restarted my computer (can't hurt?)
  • Made sure the node_modules folder is not read only

Appreciate your time!

I get this error when running Visual Studio Code because the typescript compiler watches files and locks them (see https://github.com/Microsoft/vscode/issues/28593). The solution is to temporarily close VS Code when dealing with NPM. Perhaps you have something watching files?
