重新启动我的机器后，当我的登录脚本调用它时，我可以看到 virtualenv 无法设置。
我的 .bashrc 包含
export WORKON_HOME=~/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
错误看起来像
Traceback (most recent call last):

File "/Library/Python/2.7/site-packages/virtualenvwrapper/hook_loader.py", line 12, in <module>

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=/usr/bin/python and that PATH is set properly.
据我所知，错误消息中提到的项目看起来还不错，

我对 Python 还很陌生，但 virualenv 已经工作了几个星期，并且已经重启了很多次，所以我对这一切感到很困惑。任何指针都非常感谢。
