这是已安装的库pip冻结：

certifi==2018.8.24
chardet==3.0.4

这也是INSTALLED_APPS：

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.admin',

    'subscriptions2',
    'aggregator',
    'blog',
    'captcha',
    'snowpenguin.django.recaptcha2',
    'markup_deprecated',
)

我不确切知道问题出在哪里或如何解决。我一直在搜索此ImportError，但没有谈论这样的错误。！

在django-1.8中，一些不推荐使用的元素have been removed [Django-doc]：

django.middleware.doc.XViewMiddleware将被删除。请改用django.contrib.admindocs.middleware.XViewMiddleware。

因此，在您的MIDDLEWARE_CLASSES中，应将其替换为：

# settings.py

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.admindocs.middleware.XViewMiddleware',
    'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware',
)

在更高版本中，MIDDLEWARE_CLASSES重命名为MIDDLEWARE。如果您升级Django版本，建议您检查deprecation page并进行相应的更改。通常，在删除一项之前，将其标记为已弃用两个版本。因此它在django-1.6中被标记为不推荐使用。
