Google App Engine: No module named google.api

Question

I have installed the latest version of google cloud sdk, google-cloud-sdk-app-engine-python on my Ubuntu PC as mentioned in the docs in-order to test google-cloud-endpoints-framework sample app.

But on invoking an api request, I got the below traceback. Seems like there is a conflict between google package inside GAE sdk and the google package installed automatically to the lib folder because of google-endpoints package.

$ dev_appserver.py app.yaml

I tried creating a seperate virtualenv but the problem still exists.

Answer 1

Your error :

ImportError: No module named google.api

So you need first to install gcloud python module and google-api-python-client module with:

pip install --upgrade gcloud
pip install --upgrade google-api-python-client

from here

I had a similar issue with other Google packages in my lib directory. I solved/monkey patched it using the following code in my appengine_config.py file:

import sys
import os
import google
from google.appengine.ext import vendor
lib_directory = os.path.dirname(__file__) + "<relative path to lib dir>"
google.__path__.append(os.path.join(lib_directory, 'google'))
logging.info("importing lib %s" % (lib_directory))
vendor.add(lib_directory)

Here is the reply from a google guy..

Local development with endpoints framework v2 isn't currently supported, you'll need to deploy the app.
