I'm receiving the following error when executing the dev_appserver.py:

from google.auth import app_engine
File "/google/google-cloud-sdk/platform/google_appengine/google/appengine/tools/devappserver2/    python/runtime/sandbox.py"
, line 1147, in load_module
    raise ImportError('No module named %s' % fullname)
ImportError: No module named google.auth

Odd thing is when I deploy the app, it works fine.

I tried:

  1. dev_appserver.py MY_DIRECTORY
  2. cd /google/google-cloud-sdk/bin/; python dev_appserver.py MY_DIRECTORY
  3. python dev_appserver.py hello_world/
  4. Installed updated gcloud components install app-engine-go

Additional info:

  1. No virtual env is being used.
  2. path to dev_appserver: /google/google-cloud-sdk/bin/dev_appserver.py
  3. I'm using Google's Console Cloudshell

I solve the issue:

The dev_appserver.py was not using the modules in my lib folder. Instead it was using the packages on my computer. To eliminate the issue, I removed all Google packages from my local machine and it works great now.

  • What libraries did you vendor in your app's lib dir? Commented Mar 9, 2018 at 14:24
  • Just added my lib folder. Commented Mar 9, 2018 at 14:52
  • Hm, you appear to indeed have google-auth installed. Do you see the google/auth/__init__.py and google/auth/app_engine.py files under lib? Commented Mar 9, 2018 at 15:01
  • Wait, I see a google_auth-1.4.1-py3.6... file in lib - is that a python3 version of the library by any chance? You need a python 2.7 one... Commented Mar 9, 2018 at 15:03
  • Thanks @DanCornilescu. Yep, google/auth/__init__.py exists. How would I uninstall google_auth-1.4.1-py3.6..' from the /lib folder and install the python 2.7 version. To be clear, I'm using python 2.7. Commented Mar 9, 2018 at 15:18

I solved this issue by above comment:

Yes, I have the following in appengine_config.py:

from google.appengine.ext import vendor

vendor.add('lib')

I managed to resolve the module loading issue by using the following instead:

appengine_config.py

import os
import google
from google.appengine.ext import vendor

lib_directory = os.path.dirname(__file__) + '/lib'

# Change where to find the google package (point to the lib/ directory)
google.__path__ = [os.path.join(lib_directory, 'google')] + google.__path__

# Add any libraries install in the "lib" folder.
vendor.add(lib_directory)

Thanks @Axa Cheng. I implemented but ran into the next error: Ena ble it by visiting https://console.developers.google.com/apis/api/sheets.googleapis.com/overview?project=cloud-devshell-dev then re try. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry."> The API is enabled and the patch also gives me the following error when deploying the app: ` from pyasn1.codec.der import decoder ImportError: No module named pyasn1.codec.der`. The Sheets API has been enabled for three days.
I could solve this problem by doing what Kamran said in here.

I had very likely problem in from google.auth.crypt import base and I solved it, so you can try this.

Go to the file that has the import problem, and change manually the:

from google.auth import app_engine

To the:

import app_engine
