google.appengine.ext Python Module ImportError No

Question

Python 2.7.6, Google APIs Client Library for Python for Google App Engine, Google Developer's Guide

I'm going through the Google documentation, and trying to duplicate their example. When I run the command:

from google.appengine.ext import webapp

from Python Shell, I get the error msg:

No module named google.appengine.ext

So obviously, that file is not on my computer. I've done searches for the file on my hard drive and haven't found anything. I've run easy_install to install the Google API as instructed in the official Google Quick Start video. I'm not sure if Google's documentation is now outdated, or what is happening. Where do I get the google.appengine.ext? I'm assuming that my problem is simply that I don't have that module.

Answer 1

You may need to add the following line, incase you are running stand alone tests

 sys.path.append('/usr/local/google_appengine/')
 sys.path.append('/usr/local/google_appengine/lib/yaml/lib/')
 if 'google' in sys.modules:
     del sys.modules['google']

Answer 2

I've seen @varun answer in other question, and he use insert instead of append, and then this work perfectly, at least for me.

sys.path.insert(1, '<yourFolder>/google_appengine')
sys.path.insert(1, '<yourFolder>/google_appengine/lib/yaml/lib')
if 'google' in sys.modules:           
    del sys.modules['google']

Answer 3

The google.appengine.ext means google/appengine/ext it is just like the packages directory in Eclipse

Answer 4

App Engine samples presume that you have the App Engine SDK installed:
