title: Issue in installing grunt-cli
body: <p>I'm trying to install grunt-cli. Here is the command I'm executing:</p>
  
  <pre><code>  npm install -g grunt-cli
  </code></pre>
  
  <p>But I'm getting the following error message. My machine is running under corporate proxy. Is it due to that?? Could someone please let me know how to resolve this issue.</p>
