How to generate AngularJS project?

Help, generate project for angular. I installed node.js v0.12 using homebrew, npm v2.5.1. Next I installed the yeoman and generator-angular. Began to generate project using the command:

yo angular

but it is not established as necessary node.js >= v0.12.0 and npm v2.5.1 and more. I deleted everything, downloaded v0.10.34 from the official website, but there version npm 1.4.6. I tried to update using the command:

npm install npm -g    

but it gives an error and then any command npm:

npm: command not found

How to solve the problem?
