Answer 1

First: Install CLI by writing->>>: npm install -g @angular/cli Second:if you want check your version writing -->>>: *ng v OR ng version*

Answer 2

I think you need to check the version of the npm package instead. What you typed means you are asking it to check the version by running angular installed as a program on the computer, not an npm package. The command you want is npm list ng --depth=0. This gives you the version installed with npm. It takes it out of the list command you were using.

If you want to be able to use angular from the command line, you need to install angular-cli as well.
