# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),

如果您只从项目中运行一个站点，则不需要站点框架，因此最简单的修复方法是从INSTALLED_APPS中删除以下项目，错误应该消失：

'django.contrib.sites'

您还可以从shell重新创建缺少的Site对象。运行python manage.py shell然后：

from django.contrib.sites.models import Site
Site.objects.create(pk=1, domain='www.xxx.com', name='xxx.com')

我想这可能会对你有帮助。
