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:

解决方案

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?

解决方案

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.
