pythonpath for google app engine in pydev eclipse

Question

I have google app engine installed to /home/mydev folder such that dev_appserver.py is in /home/mydev/google_appengine directory.

In eclipse helios,I have pydev and for my project's PYTHONPATH,I added the path /home/mydev/google_appengine/lib under external libraries.

Still,pydev compains it cannot resolve

import webapp2

Any idea how to solve this?

Answer 1

I am using Eclipse Indigo 3.7.2, PyDev 2.2.3, and GAE 1.6.5 and I get the same problem by pointing external libraries to /home/mydev/google_appengine/lib (or the equivalent on my machine), but it resolves when I point the external libraries to /home/mydev/google_appengine , the parent directory.

Hope this helps (this is an empirical solution that worked for me and have no specific reason why it works).

Answer 2

You need to add /home/mydev/google_appengine/lib/webapp2 in PYTHONPATH. Because within this directory only webapp2 module resides.

Answer 3

When inside PyDev, have you created your project as a google app engine project (that's a project type that PyDev has)... The wizard to create that kind of project should automatically get the google app libraries so that your import works.
