Virtualenv在OS X Yosemite OSError上失败

Question

我最近更新到OSX Yosemite，现在我不能使用virtualenv/pip。

每当我执行：

virtualenv env 

它抛出一个：

OSError: Command /Users/administrator...ux/env/bin/python2.7 -c "import sys, pip; sys...d\"] + sys.argv[1:]))" setuptools pip failed with error code 1 

这堆栈跟踪点子内抛出：

ImportError: cannot import name HTTPSHandle 

有没有其他人遇到这个错误？这些问题表明更新自制软件来解决这个问题。我已经做了，但问题仍然存在。

• ImportError: cannot import name HTTPSHandler using PIP
• ImportError: cannot import name HTTPSHandler installing get-pip.py
• ImportError: cannot import name HTTPSHandler using Brew

brew uninstall python 

brew install python 

pip install --upgrade pip 

*注意：您还需要为您正在处理的任何当前项目执行全新的pip安装。
