Django-Python RunServer时的其余框架错误

ImportError: No module named urllib

服务器错误消息：[17 / Dec / 2014 16:26:45]“ GET / HTTP / 1.1” 500 59

这正在检查python是否返回模块：

>>> import django.utils.six.moves
>>> import django.utils.six.moves.urllib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named urllib
>>>

我当前的python版本是2.7.2，Django是1.5.1，其余框架在2.7 site-package中。我已经尝试过多次卸载并重新安装Django并得到相同的错误。这是在Mac OS X 10.9.5上运行的，请帮助我，我已经参加了5个小时。
