Virtualenv因OSError而在OS X Yosemite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

并且在该堆栈内跟踪pip抛出:

ImportError: cannot import name HTTPSHandle

有没有其他人遇到过这个错误？这些问题建议更新自制软件以解决问题.我已经完成但问题仍然存在.

• ImportError:无法使用PIP导入名称HTTPSHandler
• ImportError:无法导入名称HTTPSHandler安装get-pip.py
• ImportError:无法使用Brew导入名称HTTPSHandler
