Django 1.11: AttributeError: 'module' object has no attribute 'setup_environ'

This is related to a bug I raised against app engine while tying to migrate from django 1.5 to 1.11.

The issue is I have an app running on app engine using django 1.5.

Recently I was making a number of major updates to the app and decided to convert to django 1.11 as part of that update.

Everything seemed to work fine on my local dev_appserver, but when I deployed it to app engine, it threw an error similar to this...

ERROR    2019-02-28 19:01:49,710 wsgi.py:263]

Traceback (most recent call last):

    management.setup_environ(settings, original_settings_path=settings_path)

AttributeError: 'module' object has no attribute 'setup_environ'

I downloaded the app back to my local development server and built a clean python environment using only the exact modules I needed - and then I saw the same setup_environ error.

The module indicated has the following code which is throwing the error.

try:
  settings = __import__(settings_path)
  management.setup_environ(settings, original_settings_path=settings_path)
except ImportError:
    pass

I changed the code to 

try:
  settings = __import__(settings_path)
  management.setup_environ(settings, original_settings_path=settings_path)
except AttributeError:
  django.setup()
except ImportError:
    pass

And everything works fine.

My problem is that the changed module appears to be inside the google-cloud-sdk and therefore I cannot change it in production.

My app.yaml point to django 1.11

I've searched the net and no one seems to have encountered this problem before...there is a lot about setup_environ, but nothing that addresses this particular issue.

I even raised a ticket against app engine (https://issuetracker.google.com/issues/124539522) but received a reply that it was a django problem.

Question is - has anyone else come across this problem in the app engine environment - and how did you resolve it?

Thanks!
