这是已安装的库 pip freeze:

certifi==2018.8.24 
chardet==3.0.4

这里还有 INSTALLED_APPS:

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

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

我不知道问题出在哪里，也不知道该如何解决。我一直在搜索这个 ImportError 但没有人在谈论这样的错误。!

请您参考如下方法:

在django-1.8一些弃用的元素 have been removed ^[Django-doc] :

django.middleware.doc.XViewMiddleware will be removed. Use django.contrib.admindocs.middleware.XViewMiddleware instead.

所以在您的MIDDLEWARE_CLASSES中，您应该将其替换为:

# settings.py 
 
MIDDLEWARE_CLASSES = ( 
    'django.middleware.common.CommonMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware', 
    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    <b>'django.contrib.admindocs.middleware.XViewMiddleware'</b>, 
    'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware', 
)

在以后的版本中，MIDDLEWARE_CLASSES 被重命名为 MIDDLEWARE。如果你升级 Django 版本，我建议你检查 deprecation page并做出相应的改变。通常一个项目在被删除之前被标记为弃用两个版本。所以它在 django-1.6 中被标记为已弃用.
