Exception Value: Site matching query does not exist.

你知道是什么导致了这个错误吗？

按照哈克哈姆斯顿的指示Site.objects.get(pk=settings.SITE_ID)返回了这个错误

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 ofexample.com`

您SITE_ID的设置值可能与对象的主键不对应Site。您可以通过运行以下命令进行验证：

$ ./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>

如果最终命令的响应不是Site对象（它可能会引发Site.DoesNotExist异常），那么这就是问题所在。您可以通过不设置来解决它，SITE_ID如果您不使用django.contrib.sites ，这是不必要的。

我知道这听起来可能很奇怪，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发生冲突。
