【问题描述】：

我最近安装了 OS X Mavericks。我可以访问我之前创建的虚拟环境，但我无法创建一个新环境：

Christophers-MacBook-Pro-2:~ christopherspears$ mkvirtualenv bottle_todo
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

我查看了 /usr/local/bin/virtualenv：

#!/usr/local/opt/python/bin/python2.7
# EASY-INSTALL-ENTRY-SCRIPT: 'virtualenv==1.10.1','console_scripts','virtualenv'
__requires__ = 'virtualenv==1.10.1'
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('virtualenv==1.10.1', 'console_scripts', 'virtualenv')()
    )

果然路径/usr/local/opt/python/bin/python2.7不退出。早些时候，我遇到了这个问题：

Terminal issue with virtualenvwrapper after Mavericks Upgrade

我尝试更新 virtualenv 无济于事：

christohersmbp2:~ christopherspears$ pip install virtualenv
Requirement already satisfied (use --upgrade to upgrade): virtualenv in /Library/Python/2.7/site-packages
Cleaning up...
christohersmbp2:~ christopherspears$ pip install --upgrade virtualenv
Requirement already up-to-date: virtualenv in /Library/Python/2.7/site-packages
Cleaning up...
christohersmbp2:~ christopherspears$ mkvirtualenv test
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

【问题讨论】：

which python 对你说了什么？
我得到 /usr/bin/python
尝试重新安装 virtualenv。它应该指向那个 pyton
似乎没有用。我会更新帖子。
所以它最终奏效了？

我修好了。我不得不卸载并重新安装 virtualenv：

christohersmbp2:bin christopherspears$ sudo pip uninstall virtualenv
