Heroku Python Django应用程序部署失败：没有名为'oauth2_provider'的模块

Question

我跟随Django OAuth Toolkit tutorial。我已经在安装了Django OAuth Toolkit的本地服务器上成功运行了应用程序。

当我尝试部署到Heroku时，我在运行'$ python manage.py collectstatic --noinput'时遇到“ModuleNotFoundError：没有名为'oauth2_provider'的模块”错误。

我试图搜索Stack Overflow的类似问题，但无法找到。我在Stack Overflow上看到了很多关于collectstatic的问题，但我认为这不是我的问题。

我的回溯是这样的：

我的settings.py已安装的应用程序如下：

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',
]

我正在使用Python 3.6.1，我的requirements.txt如下：

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

Answer 1

你在requirements.txt文件中遗漏了这个包。所以在那里添加django-oauth-toolkit它应该工作

Answer 2

尝试安装包“django-oauth-toolkit”，执行：

pip install -U django-oauth-toolkit

要么

pip3 install -U django-oauth-toolkit

另一个修复可能是升级你的python版本，我遇到python 2.7的问题，但不是python 3.5
