import OAuth2Authentication ImportError：没有名为“ oauth2_provider.ext”的模块

问题描述

我正在尝试通过python projcet中的Facebook登录。它一直告诉我ImportError：每当我使用终端迁移该模块时，都没有名为'oauth2_provider.ext'的模块

我是使用pip Frozen安装的：

INSTALLED_APPS = [..,'oauth2_provider','social_django','rest_framework_social_oauth2',]

TEMPLATES = [ ...,'OPTIONS': {...,'social_django.context_processors.backends','social_django.context_processors.login_redirect',],AUTHENTICATION_BACKENDS = (
           'social_core.backends.facebook.FacebookOAuth2','rest_framework_social_oauth2.backends.DjangoOAuth2','django.contrib.auth.backends.ModelBackend',)

        SOCIAL_AUTH_FACEBOOK_PROFILE_EXTRA_ParaMS = {
            'fields': 'id,name,email'
        }
    

和urls.py中：

        in urlpatterns = [...,..,url(r'^api/social/',include('rest_framework_social_oauth2.urls')),]

解决方法

由➡️pip install django-rest-framework-social-oauth2解决

不是那个导致错误的版本▶️django-rest-framework-social-oauth2 == 1.0.4 错误消失了
