获取错误：django.core.exceptions.AppRegistryNotReady：在django rest框架中安装oauth2提供程序时未装载应用程序

Question

我试图在Django中安装django-oauth2提供程序。迁移过程中安装和配置settings.py，之后，我收到错误，如：

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

settings.py

INSTALLED_APPS = [ 
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'rest_framework', 
    'hello_api', 
    'rest_framework.authtoken', 
    'provider', 
    'provider.oauth2', 
] 

MIDDLEWARE = [ 
    'django.middleware.security.SecurityMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware', 
    'django.middleware.common.CommonMiddleware', 
    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    'django.contrib.messages.middleware.MessageMiddleware', 
    'django.middleware.clickjacking.XFrameOptionsMiddleware', 
    #'corsheaders.middleware.CorsMiddleware', 
] 
ROOT_URLCONF = 'hello_api2.urls' 

TEMPLATES = [ 
    { 
     'BACKEND': 'django.template.backends.django.DjangoTemplates', 
     'DIRS': [], 
     'APP_DIRS': True, 
     'OPTIONS': { 
      'context_processors': [ 
       'django.template.context_processors.debug', 
       'django.template.context_processors.request', 
       'django.contrib.auth.context_processors.auth', 
       'django.contrib.messages.context_processors.messages', 
      ], 
     }, 
    }, 
]

你不应该使用django-oauth2-provider，因为它不再被维护。最近一次更新是3年前。

你提供的回溯在Django 1.9+的bug报告中。

https://github.com/caffeinehit/django-oauth2-provider/issues/136

但是可以使用的Django OAuth的工具包，其提供所有的类似和增强的功能，同时还支持的Django> = 1.8.For的更多信息， read from here。可以使用this source。
