Python2 工作正常，但 pip2 已损坏，我无法安装任何软件包。如何重新安装 pip 以安装软件包？

Answer 1

看起来你正在尝试使用 pip 的版本 21，因此值得注意的是 pip 在 2021 年 1 月删除了对 Python 2 的支持，因此 Pip 版本 20.3 是最后一个支持 [=23 的版本=] 2.7.

这是来自 get-pip.py 的弃用通知：

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

话虽如此，请参阅 or Can I force pip to reinstall the current version? 重新安装 pip。

如果你卸载了pip，你仍然可以使用Python2.7版本的get-pip.py来安装它。

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py
python2 get-pip.py
