title: npm installation issues
body: <p>I have installed express, fs and couple of packages.
  when I do </p>
  
  <pre><code>npm ls
  </code></pre>
  
  <p>I am getting the following Error:</p>
  
  <pre><code>â   âââ mime@1.2.6
  âââ fs@0.0.0 extraneous
  âââ node-uuid@1.4.0
  
  npm ERR! extraneous: fs@0.0.0 /home/user123/trail/node_modules/fs
  npm ERR! extraneous: express@3.0.5 /home/user123/trail/node_modules/express
  npm ERR! not ok code 0
  </code></pre>
  
  <p>I am not sure how to get this ERR out?
  I am able to run my sample application using the azure and express.
  not sure if it is taking from sudo npm ? if so how.
  I want to know when will it take from sudo npm list (global)? and when from npm list (locally).</p>
  
  <pre><code>sudo npm ls
  </code></pre>
  
  <p>there are no Errors</p>
