title: PyDev Code Analysis not working in Aptana Studio
body: <p>I have a couple of Python projects which I imported into Aptana using "<code>Import</code> --> <code>Existing Folder as New Project</code>"</p>
  
  <p>The import is successful, I can run and debug scripts inside Aptana. However, for some reason I cannot get PyDev's code analysis working.</p>
  
  <p>All settings in <code>Window</code> -> <code>Preferences</code> -> <code>PyDev</code> -> <code>Editor</code> -> <code>Code Analysis</code> seem to be correct:</p>
  
  <ul>
  <li><code>Do code analysis?</code> is checked</li>
  <li><code>pep8.py</code> is set to run and report results as Warnings</li>
  </ul>
  
  <p>I run it by right-clicking on a file and choosing "Run Code Analysis":

  <p>The following window appears shortly, but then it closes and I see no results (i.e. 
  nothing on the "Problems" view, no red underscore under parts of the code, etc.):

  <p>Any idea what might be wrong? Or where I should look for to get more details on what's going on under the hood (log files, etc.)?</p>
