如何在Windows上使用python 2.6安装pip [英] How to install pip with python 2.6 on Windows

问题描述

我正在尝试在我的开发机上使用python 2.6安装pip，以尝试匹配也使用python 2.6的部署环境.

Python 2.6安装成功.我已经尝试使用get-pip.py来安装pip，如此处 https://pip所述. pypa.io/en/stable/installing/和 https://bootstrap.pypa.io/2.6/get-pip.py

但是它失败并显示以下内容:

显然，升级到较新的python达不到我的目的.

建议将 URL 上的信息用于警告InsecurePlatformWarning建议我使用pip ...>安装更多的东西.

PS 我也尝试过使用setuptools-40.0.0中的简易安装，但是无法正常工作.我不确定我是否正确使用它，因为setuptools安装文档具有循环链接(从文档到Pypi，再到文档)

解决方案

对于Python 2.6，您需要较旧的setuptools.适用于Python 2.6的最新setuptools版本是 36.8

下载 setuptools-36.8.0.zip ，解压缩并运行python2.6 setup.py install.

之后 get-pip.py 应该为您安装pip.

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

Im attempting to install pip with python 2.6 on my dev machine to try to match a deployment environment that also uses python 2.6.

Python 2.6 is installed OK. I've tried installing pip using get-pip.py as outlined here https://pip.pypa.io/en/stable/installing/ with the version of the get-pip.py script from https://bootstrap.pypa.io/2.6/get-pip.py

However it fails with the following:

C:\users\me> python get-pip.py

Obviously, upgrading to newer python defeats my purpose.

The information at the URL recommended for the warning InsecurePlatformWarning suggests that I install more things using pip... >.<

PS I've tried using easy-install from setuptools-40.0.0 as well, but I could not get this to work. I'm not sure if I'm using it correctly as the setuptools installation documentation has circular links (from the documentation to Pypi, back to the documentation)

解决方案

For Python 2.6 you need older setuptools. The last setuptools version that works with Python 2.6 is 36.8.

Download setuptools-36.8.0.zip, unpack and run python2.6 setup.py install.

After that get-pip.py should install pip for you.

The last version of pip supporting Python 2.6 is 9.0.3: https://pypi.org/project/pip/9.0.3/#files
