I have a dedicated web server which runs CentOS 6.6 我有一个运行CentOS 6.6的专用Web服务器。

I am running some script that uses Python SHA module and I think that this module is deprecated in the current Python version. 我正在运行一些使用Python SHA模块的脚本，并且我认为当前的Python版本已弃用该模块。

I am consider downgrading my Python installation so that I can use this module. 我正在考虑降级Python安装，以便可以使用此模块。

Is there a better option? 有更好的选择吗？ If not, how should I do it? 如果没有，我该怎么办？

Instead of literally downgrading, I would consider virtualenv . 我不会考虑字面的降级，而是考虑使用virtualenv 。 It lets you create isolated python environments, including the specific python version and the modules. 它使您可以创建隔离的python环境，包括特定的python版本和模块。

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. 您始终可以使用-altinstall参数安装其他版本的Python，然后在虚拟环境中运行它，或者仅使用python（version）命令运行命令。

A considerable amount of CentOS is written in Python so changing the core version will most likely break some functions. 大量的CentOS用Python编写，因此更改核心版本很可能会破坏某些功能。
