I had this problem recently running on a Windows box.

To solve: using gitbash:

npm uninstall -g @angular/cli
npm cache verify

uninstall node using the uninstall option on the Windows menu > Node using gitbash: cd ~/AppData/Roaming rm -rf npm rm -rf npm-cache

RESTART WINDOWS : You must restart windows

reinstall node.js

npm i @angular/cli -g

That worked.
