Exception Type: DoesNotExist at /admin/ 
Exception Value: Site matching query does not exist.

你知道是什么原因造成这个错误？

继哈克Harmston说明Site.objects.get(pk=settings.SITE_ID)返回此错误

在我的数据库中有一个site_id http://127.0.0.1:8000/' which is the domain name that i used instead of example.com`

你在你的数据库有从settings.py文件的ID的网站对象？ – StefanNch 2012-04-10 11:05:38

你忘了运行执行syncdb？ – 2012-04-10 11:06:17

@burhan django-userena有两个settings.py，一个在'demo project'文件夹内，另一个在它外面，我在'demo project'文件夹中运行syncdb，但是我正在编辑其他settings.py文件，没有manage.py文件，因此我无法运行syncdb – user 2012-04-10 17:02:32

我知道这听起来不可思议，但我曾经看到过这样的错误。尝试删除django.contrib.sites。它与该人安装的另一个应用程序相撞。

建议有人批发删除依赖项是不明智的。他们可能不需要站点的contrib包，但他们可能还是其第三方应用程序可能需要它的一个。此外，如果有一个网站包冲突，这与包装，而不是网站的问题。你不应该写任何与Django的东西冲突的东西，不管它是否可选。 – 2012-04-10 14:23:56

你SITE_ID设置的值可能不会与Site对象的主键相对应。您可以通过运行这个验证：

$ ./manage.py shell 
Python 2.7.1 [...] 
>>> from django.contrib.sites.models import Site 
>>> from django.conf import settings 
>>> Site.objects.get(pk=settings.SITE_ID) 
<Site: example.com>

如果最后命令的响应不是Site对象（这将会有可能提出一个Site.DoesNotExist除外），那么这就是问题所在。您可以通过不设置SITE_ID，如果你不使用django.contrib.sites这是不必要的解决这个问题。

请阅读我的编辑 – user 2012-04-11 09:23:56

或者，你可以在DB编辑SITE_ID – 2017-07-12 07:04:40
