title: angular-cli different versions in the same computer
body: <p>I'm working with Angular2 in several projects. Each of this projects uses a different version of <code>angular-cli</code>, so, I need to be able to run and compile for production each separately with the correct version of <code>angular-cli</code>. When I installed <code>angular-cli</code> locally using <code>save-dev</code>, ng commands not found so I cannot create a build distribution for the project.</p>
  
  <p>So the question are, how can I have multiples <code>angular-cli</code> version in the same machine, without installed globally (with -g option)?, it is possible run ng commands without installing <code>angular-cli</code> globally?</p>
