python - 不能再用 python 2.7 安装 pip 了吗？

Question

我想使用与 python 2.7(但不是 3.8)兼容的 python 脚本
我需要 pip 才能使脚本正常工作，但看起来我无法再安装 pip 了？我尝试使用 get-pip.py ，但它不起作用:

user@DESKTOP-J9T7UBF
$ get-pip.py
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 Please upgrade your Python as Python 2.7 is no longer maintained.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.

Answer 1

最新的 pip 有 dropped support for Python 2
并且您无法使用 Python 2.7 通过 get-pip.py 安装最新的 pip。
更新:在这里找到了 Python 2.7 脚本的答案

您应该升级到 Python 3。
如果您使用只有 Python2.7 的 Linux 发行版，则可以使用 Linux 包管理器。注意 - 它安装了来自上述脚本的旧版本的 Pip。

If you installed Python from a package manager on Linux, you should always install pip for that Python installation using the same source. https://pip.pypa.io/en/stable/installing/ --> https://packaging.python.org/guides/installing-using-linux-tools/
