title: NODE_PATH no effect
body: <p>I would like that </p>
  
  <pre><code>~ $ npm install express"
  </code></pre>
  
  <p>will not install express in my home folder, but instead in <code>~/apps/node_modules</code>.</p>
  
  <p>So I inserted this <code>export NODE_PATH=/home/a/apps/node_modules</code> in <code>.bashrc</code> and than I did <code>source .bashrc</code>.</p>
  
  <p>Unfortunately, <code>npm install express</code> still installs it in <code>/home/a/node_modules</code> and <code>npm install -g express</code> require root/Administrator.</p>
  
  <p>How is it possible that npm install packages in <code>/home/a/apps/node_modules</code>?</p>
