pip - 如何在 Windows 上使用 python 2.6 安装 pip

Question

我正在尝试在我的开发计算机上安装带有 python 2.6 的 pip，以尝试匹配也使用 python 2.6 的部署环境。

Python 2.6 安装正常。我尝试使用 get-pip.py 安装 pip，如此处所述 https://pip.pypa.io/en/stable/installing/使用 https://bootstrap.pypa.io/2.6/get-pip.py 中的 get-pip.py 脚本版本

但是它失败并显示以下内容:

C:\users\me> python get-pip.py
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

显然，升级到更新的 python 违背了我的目的。

信息位于URL建议警告 InsecurePlatformWarning 建议我使用 pip 安装更多东西...>。<

PS 我也尝试过使用 setuptools-40.0.0 中的简易安装，但无法使其正常工作。我不确定我是否正确使用它，因为 setuptools 安装文档有循环链接(从文档到 Pypi，回到文档)

Answer 1

对于 Python 2.6，您需要较旧的setuptools。与 Python 2.6 一起使用的最后一个 setuptools 版本是 36.8 .

下载setuptools-36.8.0.zip ，解压并运行python2.6 setup.py install。

之后get-pip.py应该为您安装pip。

支持 Python 2.6 的最新版本 pip 是 9.0.3 : https://pypi.org/project/pip/9.0.3/#files
