Nvm is managing my node versions , it ran in my laptop some weeks before.

Update

After npm cache clean and installing cli again it gives me this error

• Parham Alvani: are you using standard npm repository or it is a private npm repository ?

Answer 1

I ran into the same issue - the latest version of npm uses self healing cache.
All you need to do is run:

npm cache verify

After that run:

npm i -g @angular/cli

That did the trick for me

Answer 2

I was having a problem installing the Angular CLI with npm and found that I needed to disable auth in my .npmrc file.
