Heroku Python Django App Deployment Failure: No module named 'oauth2_provider'

问题

I am following the Django OAuth Toolkit tutorial. I have the app running successfully on my local server with Django OAuth Toolkit installed.

When I try to deploy to Heroku I get a "ModuleNotFoundError: No module named 'oauth2_provider'" error while running '$ python manage.py collectstatic --noinput'.

I have attempted to search Stack Overflow for similar questions but was unable to find one. I saw many questions on Stack Overflow relating to collectstatic but I do not think that is my problem.

My backtrace is as so:

My settings.py Installed Apps is as so:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    # Disable Django's own staticfiles handling in favour of WhiteNoise, for
    # greater consistency between gunicorn and `./manage.py runserver`. See:
    # http://whitenoise.evans.io/en/stable/django.html#using-whitenoise-in-development
    'whitenoise.runserver_nostatic',
    'django.contrib.staticfiles',
    'oauth2_provider',
    'corsheaders',
]

I am using Python 3.6.1 and my requirements.txt is as so:

dj-database-url==0.4.1
Django==1.11.1
gunicorn==19.6.0
psycopg2==2.6.2
whitenoise==3.2

回答1:

You're missing this package in your requirements.txt file. So add django-oauth-toolkit there and it should work

回答2:

Try installing the package "django-oauth-toolkit", execute:

pip install -U django-oauth-toolkit

pip3 install -U django-oauth-toolkit

Another fix could be upgrade your python version, I got this problem with python 2.7, but not with python 3.5
