Question

I’m running from appname import model, which gives me:

ImportError: No module named google.appengine.api

So I add the following Python path (the only path I could find):

PYTHONPATH=/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/:~/src/appname/src/ python

And then I run the command again. But that tells me:

ImportError: No module named yaml

I’m running Mac OS X Snow Leopard and the latest GAE. Any tips? All I want to do is run some of the methods in my model.

From dev_appserver.py:

DIR_PATH = os.path.abspath(os.path.dirname(os.path.realpath(__file__)))
# ...

EXTRA_PATHS = [
  DIR_PATH,
  os.path.join(DIR_PATH, 'lib', 'antlr3'),
  os.path.join(DIR_PATH, 'lib', 'django'),
  os.path.join(DIR_PATH, 'lib', 'fancy_urllib'),
  os.path.join(DIR_PATH, 'lib', 'ipaddr'),
  os.path.join(DIR_PATH, 'lib', 'webob'),
  os.path.join(DIR_PATH, 'lib', 'yaml', 'lib'),
]
# ...
sys.path = EXTRA_PATHS + sys.path

I think it should work if you put these bits in a separate script, and import it before importing your own code.

Or, as you’ve pointed out, use the Appengine console in the SDK (but that’s not there for Linux users).
