Django错误:无法导入csrf.py

我的Django应用程序突然坏了,我不明白为什么。我现在甚至不能让它运行。我正在运行修订版11798。

当我使用独立服务器测试我的应用程序时,它突然开始不导入csrf。我以前让它工作得很好。我试着通过使用shell来查看发生了什么,结果如下:

$ ./manage.py shell
Python 2.6.3 (r263:75184, Oct  2 2009, 07:56:03) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
>>> import django
>>> from django import middleware
>>> from django.middleware import csrf
Traceback (most recent call last):
  File "<console>", line 1, in <module>
ImportError: cannot import name csrf
>>>

我检查了文件系统,看看文件是否在那里,它是否完整。我非常困惑。有人能帮我吗?

Django错误如下:
