virtualenvwrapper安装错误

Question

我已经通过pip安装了pip和virtualenvwrapper。我将以下行添加到我的.bashrc中

# virutalenvwrapper                                                                                                                                                                                                                                        
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh

一旦我找到.bash_profile，我就会收到一个错误

$ source ~/.bash_profile
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named virtualenvwrapper.hook_loader
virtualenvwrapper.sh: There was a problem running the initialization hooks. 

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenv has been installed for
VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/2.7/bin/python and that PATH is
set properly.

这是什么错误？我见过很多人都有同样的错误，我也尝试了上面列出的建议，但似乎没有一个对我有效。

我运行的是OS X Mountain Lion和Python 2.7。
