title: NodeJS NPM Proxy error when installing grunt
body: <p>When I'm trying to install <code>grunt</code> via <code>npm</code>, I'm getting a following error:</p>
  
  <pre><code>C:\Program Files\nodejs\node_modules\npm&gt;npm install -g grunt
  npm ERR! network connect ETIMEDOUT
  npm ERR! network This is most likely not a problem with npm itself
  npm ERR! network and is related to network connectivity.

  <p>I´m using enterprise proxy configurations, and I believe that I'm having this error because of its configurations. What do I need to change in order to install grunt successfully?</p>
