我正在尝试创建一个virtualenv,我将在OSX El Capitan上运行旧版本的Django(1.4.2)和特定版本的Python(2.7.8)。以下是我经历的步骤:
我使用此工作流下载并编译了Python 2.7.8: Is it possible to install another version of Python to Virtualenv?
当我尝试使用指向我新编译的Python2.7.8的--python标志创建一个新的virtualenv时,我收到一条如下所示的错误消息:
Complete output from command /Users/luka/xxx/virtu...y2_7_8/bin/python2.7 -c "import sys, pip; sys...d\"] + sys.argv[1:]))" setuptools pip wheel:

ImportError: cannot import name HTTPSHandler
如果我用--no-setuptools标志重新运行相同的命令,一切正常,我可以访问我需要的Python版本,但我没有在site-package目录中的pip和setuptools,这是一个问题,因为现在我无法在virtualenv中安装特定版本的Django。我可以简单地将现有的系统级pip安装复制到我的virtualenv中,或者以其他方式安装pip吗?

您可以在新的virtualenv using the get-pip.py
script中安装pip
:
get-pip.py
,例如使用wget或curl python get-pip.py
