title: Trouble installing Angular-hint
body: <p>Recently I found this article (<a href="http://blog.thoughtram.io/angularjs/2014/11/06/exploring-angular-1.3-angular-hint.html" rel="nofollow">http://blog.thoughtram.io/angularjs/2014/11/06/exploring-angular-1.3-angular-hint.html</a>), it seems like Angular-hint is very useful for developer. So, I try to install Angular-hint with this command:</p>
  
  <pre><code>npm install angular-hint
  </code></pre>
  
  <p>During the installation, I see angular-hint folder with files created in <code>node_modules</code> folder. But at the end of installation, everything is gone. In the command window, I saw this:</p>
  
  <pre><code>E:\www\angularjs\angular-hint\node_modules\angular-hint\node_modules\angular-hint-log\node_modules\karma\node_modules\socket.io\node_modules\socket.io-client\node_modules\ws&gt;node "C:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin\....\node_modules\node-gyp\bin\node-gyp.js" rebuild
  npm ERR! EEXIST, open 'C:\Users\MyPC\AppData\Roaming\npm-cache\50d41671-che-browserify-4-2-3-package-tgz.lock.STALE'
  File exists: C:\Users\MyPC\AppData\Roaming\npm-cache\50d41671-che-browserify-4-2-3-package-tgz.lock.STALE
  Move it away, and try again.

  </code></pre>
  
  <p>How can I get it properly installed?</p>
