title: npm install module in current directory
body: <p>When I run:</p>
  
  <pre><code>npm install my-app
  </code></pre>
  
  <p>The app is installed into node_modules/my-app/...</p>
  
  <p>I also tried</p>
  
  <pre><code>npm install -g my-app
  </code></pre>
  
  <p>But that doesn't work either.</p>
  
  <p>How can I install the module straight into the current directory?</p>
