sudo npm install -g angular-cli

Same problem here.
I had node version 4.5 and npm 2.15.9 and had the same issue. I saw that angular-cli requires npm 3.x and so installed node 6.6.0 which includes npm v3.10.3. I still get errors:

After some research I found this: #1190

This helped me. Just deleted angular-cli and then install it. Worked for me

@bernhardwaidacher thanks mate. It helped me too.

Please close this issue

I was having the same issue for checking my version and generating a new project. I did npm install -g portfinder and then npm install portfinder in the project folder to start the ng serve process.

I just went through this over and over. If nothing else works you have to search for the old version of cli and delete @angular/cli manually. Then the new one can be installed.

brew install angular-cli
working for me

[alepenchel]

brew install angular-cli
