ubuntu ng commands wont work

Im trying to make angular-cli work in ubuntu. So i installed it, but i run into a problem.

currently im working in root.

After i run npm install -g angular-cli and type ng help or any of the ng commands, i get the following in the console: ( tried ng serve)

What is that? how can i fix so ng work? how can i exit it?

Why is it not listing the ng help or any of the commands as it should?
