Python: No module named core.exceptions
<p>I'm trying to get Google AppEngine to work on my Debian box and am getting the following error when I try to access my page:</p>

<pre><code>&lt;type 'exceptions.ImportError'&gt;: No module named core.exceptions
</code></pre>

<p>The same app works fine for me when I run it on my other Ubuntu box, so I know it's not a problem with the app itself. However, I need to get it working on this Debian box. It originally had python 2.4 but after AppEngine complained about it I installed the python2.5 and python2.5-dev packages (to no avail). </p>

<p>I saw on this <a href="http://groups.google.com/group/google-appengine/browse_thread/thread/8f2459d2df9d735a/df2b1e9bb76f87c0?show_docid=df2b1e9bb76f87c0&amp;fwc=1" rel="nofollow">Google Group post</a> that it may be due to the version of AppEngine and just to reinstall it, but that didn't work. Any ideas?</p>

<p>Edit 1: Also tried uninstalling python2.4 and 2.5 then reinstalling 2.5, which also didn't work.</p>

<p>Edit 2: Turns out when I made AppEngine into a CVS project it didn't add the core directory into my project, so when I checked it out there literally was no module named core.exceptions. Re-downloading that folder resolved the problem.</p>

<p><code>core.exceptions</code> is part of django; what version of django do you have installed? The AppEngine comes with the appropriate version for whatever release you've downloaded (in the lib/django directory). It can be installed by going to that directory and running <strong><code>python setup.py install</code></strong></p>
