Django and Google App Engine Assistant did not find ipaddr module

Question

I am trying to run Django on GAE using this tutorial .

When I run python manage.py runningerver, I get stacktrace below. I am new to django and python, so I don't know what my next steps are (this is Ubuntu Jaunty btw). Django does not seem to find the GAE ipaddr module that comes with SDK 1.3.1.

How to get django to search for this module?

Answer 1

This also happens with app-engine-patch

The solution is to add $GOOGLE_APP_ENGINE/lib/ipaddrto your pythonpath, as you should have done with other dependencies like antlr3 or yaml.

, ipaddr . , D:\Python26\Lib\site-packages ipaddr.pth :

D:\Program Files\Google\google_appengine\lib\ipaddr

.

One more note: you do not need to install Python for Windows, as suggested, since it does not automatically pick up the appengine SDK (or at least it doesn't seem to me). Keep in mind that I have D: \ Program Files \ Google \ google_appengine \ in my system PATH variable, but I'm not sure if this helps (this means that I can run helper scripts there from cli).
