有没有办法让pip在多个版本的Python中都能很好地运行?例如，我想使用pip显式地将东西安装到我的站点2.5安装或站点2.6安装中。
例如，对于easy_install，我使用easy_install-2.{5,6}。
是的，我知道virtualenv，不，它不是这个特殊问题的解决方案。

例如，如果您将其他版本(例如3.5)设置为默认版本，并希望为python 2.7安装PIP:
在https://pypi.python.org/pypi/pip (tar)下载PIP 解压缩tar文件 CD到文件的目录 Sudo python2.7 setup.py install

显然，easy_install和pip有多个版本。看起来很乱。不管怎样，这是我在Ubuntu 12.10上安装Django for Python 2.7的方法:
$ sudo easy_install-2.7 pip
Searching for pip
Best match: pip 1.1
Adding pip 1.1 to easy-install.pth file
Installing pip-2.7 script to /usr/local/bin

为了在任何没有安装pip的python版本上工作，你需要下载pip并执行python*version* setup.py install。例如python3.3 setup.py install。这解决了注释中的导入错误。(@hbdgaf建议)
pip debug命令提供了一些用于调试的有用信息。它在第一行(警告之后)显示了附加的python解释器的位置。
$ pip debug

在Windows上，如果您选择在Python 3设置期间安装pip模块，则可以通过Python启动器py.exe使用给定的Python版本执行pip模块。
py -3 -m pip install packagename
py -2 -m pip install packagename
你可以更具体地请求Python的精确子版本:
py -3.6 -m pip install packagename
要获得通过启动程序可用的所有已安装Python版本的列表，请运行:
py --list
或者，您可以直接启动所需的Python可执行文件:
C:/path/to/specific/python.exe -m pip install packagename
