如何在 CentOS 上降级 python 版本?

How to downgrade python version on CentOS?(如何在 CentOS 上降级 python 版本?)

问题描述

我有一个运行 CentOS 6.6 的专用网络服务器

我正在运行一些使用 Python SHA 模块的脚本，我认为该模块在当前 Python 版本中已被弃用.

我正在考虑降级我的 Python 安装，以便我可以使用这个模块.

还有更好的选择吗?如果没有，我该怎么做?

这些是我的 Python 安装细节:

您始终可以使用 -altinstall 参数安装不同版本的 Python，然后在虚拟环境中运行它，或者只使用 python(版本)命令.

相当多的 CentOS 是用 Python 编写的，因此更改核心版本很可能会破坏某些功能.

I have a dedicated web server which runs CentOS 6.6

I am running some script that uses Python SHA module and I think that this module is deprecated in the current Python version.

I am consider downgrading my Python installation so that I can use this module.

Is there a better option? If not, how should I do it?

These are my Python installation details:

You can always install a different version of Python using the -altinstall argument, and then run it either in a virtual environment, or just run the commands with python(version) command.

A considerable amount of CentOS is written in Python so changing the core version will most likely break some functions.
