python - Django:重启后出现 "No module named context_processors"错误

Question

我有一个可以在我的 PC 上运行的 Django 站点，并且在加载它之后在我的服务器上短暂运行。我注意到我的服务器有 Django 1.6，我升级到 1.8。

重新启动后，我的网站上的任何页面都没有加载，我收到错误:

ImportError No module named context_processors

我阅读了有关 Django 和 allauth 的文档。 Django 提到在 1.8 中移动了 context_processors，allauth 说 settings.py 的 TEMPLATE_CONTEXT_PROCESSORS 中不再需要特定的 allauth 标签。

Django :https://docs.djangoproject.com/en/1.8/ref/settings/

阿劳斯:https://django-allauth.readthedocs.org/en/latest/installation.html

还有其他人遇到这个吗？我在正确的轨道上吗？我需要更改设置中的某些内容吗？我真的不知道这是 Django 还是 allauth 问题，所以不知道从哪里开始。

感谢任何帮助!

我遇到了同样的问题，但我正在从 1.9.1 升级到 1.10。我发现设置有点不同。

这是 1.9.1 的代码

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates')],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.core.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
        ],
    },
},
]

这是 1.10 的代码

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates')],
    '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',
        ],
    },
},
]

django.core.context_processors.request 行在 1.10 中无效。删除它，代码运行良好。
