title: Failing to install Yeoman (Mac OSX)
body: <p>Attempting to install Yeoman on my mac, I first tried following command from the documentation...</p>
  
  <p><code>npm install -g yo</code></p>
  
  <p>Got an error:</p>
  
  <p><code>npm ERR! Please try running this command again as root/Administrator.</code></p>
  
  <p>I tried again with:</p>
  
  <p><code>sudo npm install -g yo</code></p>
  
  <p>but it fails half-way through. This is the feedback where it fails and it repeats this pattern for a lot of failed packages.</p>
