Virtualenv返回“没有这样的文件或目录”

Question

我有过很多工作正常的虚拟机，但从今天开始，它们给了我一个错误。 我试过用easy_install-U重新安装pip和virtualenvwrapper，但错误仍然存在。有什么想法吗？

$ mkvirtualenv django
sh: 0: getcwd() failed: No such file or directory
New python executable in django/bin/python
Installing setuptools.............done.
Installing pip...............done.
