  <p>The problem is when you try to use sails: you run <code>sails new project</code>, for example, and it doesn't find sails. Investigating a little bit, I discovered npm is not installing the modules at /usr/bin. Is there some reason for that? Some config?</p>
  
  <p>The same is happening with Karma module.</p>
  
  <p>I used the nodejs from ppa, created the symbolic link for node and installed npm from the official install.sh script (<a href="https://www.npmjs.org/install.sh" rel="nofollow">https://www.npmjs.org/install.sh</a>).</p>
