title: echo $NODE_PATH returns two global installation paths
body: <p><code>echo $NODE_PATH</code></p>
  
  <p>returns</p>
  
  <p><code>/Users/swills/.npm-packages/lib/node_modules::/Users/swills/npm/lib/node_modules</code></p>
  
  <p>Running <code>npm install -g express-generator</code> installs express-generator in both:</p>
  
  <p><code>/Users/swills/.npm-packages/lib/node_modules</code></p>
  
  <p>and </p>
  
  <p><code>/Users/swills/npm/lib/node_modules</code></p>
  
  <p>Might this cause future dependency issues? If so, how can I fix this?</p>
  
  <p>I've installed node several times for updates, and once or twice to avoid having to use sudo. I think that might have something to do with it. I vaguely remember using either the first (node-and-npm-in-30-seconds.sh) or second (only-git-all-the-way.sh) option from this github gist: <a href="https://gist.github.com/isaacs/579814" rel="nofollow">https://gist.github.com/isaacs/579814</a> </p>
