Google App Engine cannot find gdata module

问题

I can run a simple "Hello World" Google App Engine application on localhost with no problems. However, when I add the line "import gdata.auth" to my Python script I get "ImportError: No module named gdata.auth".

I have installed the gdata module and added the following line to my .bashrc:

export PYTHONPATH=$PYTHONPATH:/Library/Python/2.5/site-packages/

Is there anything else I need to do? Thanks.

EDIT: The strange thing is that if I run python from a shell and type "import gdata.auth" I do not get an error.

Your .bashrc is not known to Google App Engine. Make sure the gdata directory (with all its proper contents) is under your application's main directory!

See this article, particularly (and I quote):

To use this library with your Google App Engine application, simply place the library source files in your application's directory, and import them as you usually would. The source directories you need to upload with your application code are src/gdata and src/atom. Then, be sure to call the gdata.alt.appengine.run_on_appengine function on each instance of a gdata.service.GDataService object. There's nothing more to it than that!

The gdata client library installation script installs the modules in the wrong directory for ubuntu python installation.

sudo mv /usr/local/lib/python2.6/dist-packages/* /usr/lib/python2.6/dist-packages

回答3:

try adding this to your script:

import sys
sys.path.append('<directory where gdata.auth module is saved>')
import gdata.auth
