I am on Windows and am trying to follow the instructions at http://yeoman.io/learning/index.html. So far I have successfully installed grunt-cli and bower but when I try to install yo using the following command...
npm install -g yo
...the command prompt returns this:

Does anyone have any idea what the hell this means and how I can fix it?
You can try with this : https://github.com/npm/npm/issues/7781
I think this will helps you to solve your question.
And to get node & npm in cmd. You can set node location in windows environment variable. Then restart your cmd & try again to do this.
