title: Symfony 2 cannot generate new bunlde
body: <p>I just joined ServerGrove and got a VPS. I installed Symfony 2 and unpacked it in my www folder. I ran this command <code>php app/console generate:bundle --namespace=Pixbelly/HomeBundle --format=yml</code> but I receive this error:</p>
  
  <pre><code>[InvalidArgumentException]
  There are no commands defined in the "generate" namespace.
  </code></pre>
  
  <p>I ran this command from www/Symfony and I can't figure out what is wrong.</p>
