I think this is a dupe of an old issue: #1190. It seems to be a problem with npm.

I also had this same problem what I did to fix it on Linux Mint:

• change ownership of /usr/lib/node_modules to my user to stop executing npm with sudo as this is highly discouraged.
• run npm uninstall -g @angular/cli and npm cache clean (--force)
• check if ~/.npm was clean, else rm -rf ~/-npm
• try reinstalling npm install -g @angular/cli
• go to ...node_modules/angular-cli and run npm install
• run npm install --save-dev @angular/cli@latest
• and finally i can run ng -v with no error..

but this was quite a lot of trouble I faced lol, I'm posting this here so maybe it helps other people

**Edit: **
I think many of these problems could possibly be avoided when you configure your npm's default directory according to their installation instructions on the website.
