Heroku deploy fail

[farrjp]

When trying to use the Heroku deploy button, it fails at the end of the 'build app', with the following error message included at the end of the build log:

File "/app/.heroku/python/lib/python3.6/site-packages/provider/oauth2/init.py", line 1, in
import backends
ModuleNotFoundError: No module named 'backends'
! Error while running '$ python src/manage.py collectstatic --noinput'.
See traceback above for details.
You may need to update application code to resolve this error.
Or, you can disable collectstatic for this application:
$ heroku config:set DISABLE_COLLECTSTATIC=1
https://devcenter.heroku.com/articles/django-assets
! Push rejected, failed to compile Python app.
! Push failed
