这是我的settings.py文件：

这是我的hosts.py文件：

from django.conf import settingsfrom django_hosts import patterns,hosthost_patterns = patterns('',host(r'www',settings.ROOT_URLconf,name='www'),#host(r'(\w+)','path.to.custom_urls',name='wildcard'),)

当我运行python manage.py runserver时,我收到以下错误：

django.core.exceptions.ImproperlyConfigured：无法加载Wsgi应用程序’mysite.wsgi.application’;导入模块时出错：’没有名为’django_hosts.mIDdleware.HostsRequestMIDdlewaredjango’的模块; ‘django_hosts.mIDdleware’不是包’

我究竟做错了什么？！

解决方法 你错过了一个逗号：

MIDDLEWARE_CLASSES = [    'django_hosts.mIDdleware.HostsRequestMIDdleware',# <-----    'django.mIDdleware.security.SecurityMIDdleware',]
