manage.py 运行服务器失败

Question

在 OS X 系统上，我使用的是 Python 2.7，并且创建了一个新的虚拟环境：

virtualenv bar
source bar/bin/activate
pip install django --upgrade
django-admin.py startproject foo
cd foo
python manage.py runserver

然后我立刻遇到了这个问题：

Traceback (most recent call last):
File "manage.py", line 14, in <module>

File "/Users/xyz/.virtualenvs/bar/lib/python2.7/site-packages/django/core/management/__init__.py", line 438, in execute_manager

到底出了什么问题呢？

这个问题似乎和virtualenvwrapper有关系，还有我自己的笨拙；手动创建一个虚拟环境解决了这个问题。
