Sometimes cleaning the cache helps: Update Angular after clearing Cache
It looks like it is a cache error. Reinstalling Angular CLI after clearing the npm cache. The below solution work for me, run below 3 commands one by one
npm install chokidar
npm cache clean --force
npm install -g #angular/cli#latest

This happened due to you cache got corrupted. You need to clean your cache and re-install #angular/cli.
Open command prompt and run below commands.
npm cache clean --force
npm install -g #angular/cli
