title: Composer packages update but don't install
body: <p>After doing </p>
  
  <p><code>sudo php composer.phar update</code></p>
  
  <p>I get the following:</p>
  
  <pre><code>Loading composer repositories with package information 
  Updating dependencies (including require-dev)
  Installing SOME_PACKAGE (dev-master 6fb0f62)
  Cloning SOME_TOKEN
  Writing lock file Generating autoload filesUpdating
  </code></pre>
  
  <p>But when I do <code>sudo php composer.phar install</code> I get</p>
  
  <pre><code>Loading composer repositories with package information
  Installing dependencies (including require-dev) from lock file
  Nothing to install or update
  Generating autoload files
  </code></pre>
  
  <p>Does someone have any idea on what might be happening? I have a <code>composer.json, composer.phar and composer.lock</code> all in the same folder.</p>
