  <p>No bower_components folder is created and so I get errors when referencing the bower packages.</p>
  
  <p>I am using:</p>
  
  <pre><code>OSX   10.9.5
  node  v0.12.0
  npm   v2.5.1
  bower v1.3.12
  git   v1.9.2
  </code></pre>
  
  <p>I have tried running:</p>
  
  <pre><code>$ npm cache clean
  </code></pre>
  
  <p>Any help would be much appreciated.</p>
