原文链接：统信UOS/麒麟KYLINOS上安装python特定版本

hello，大家好啊！Python作为一种广泛使用的编程语言，其版本多样性给开发者带来了既便利又挑战的情况。不同的项目可能需要不同版本的Python，而在统信UOS/麒麟KYLINOS这样的操作系统上，如何灵活地管理和切换Python版本，就成为了一个值得探讨的话题。今天，我要给大家介绍的是如何在这两个操作系统上使用pyenv来安装和管理特定版本的Python。

为什么选择pyenv？

pyenv是一个非常流行的Python版本管理工具。它的主要优势在于：

支持多版本管理：pyenv可以让你在同一台机器上安装和管理多个Python版本，非常适合需要在不同项目间切换Python环境的开发者。易于切换版本： 通过简单的命令，你可以轻松切换到不同的Python版本，无需手动配置复杂的环境变量。简化安装过程：pyenv提供了一种简化的方式来安装和编译Python，使得在不同系统上安装特定版本的Python变得更加容易。

希望这篇文章能帮助到需要在这些操作系统上使用Python的朋友们。如果你有任何问题或者更多的经验分享，请在评论区留言，我们一起讨论。如果你觉得这篇文章有用，别忘了分享转发，点个在看和关注哦！让我们一起探索和学习更多关于Python和Linux系统的知识！

1、查看系统信息

pdsyw@pdsyw-PC:~/Desktop$ cat /etc/os-version [Version] SystemName=UOS DesktopSystemName[zh_CN]=统信桌面操作系统ProductType=DesktopProductType[zh_CN]=桌面EditionName=ProfessionalEditionName[zh_CN]=专业版MajorVersion=20MinorVersion=1060OsBuild=11018.100.100pdsyw@pdsyw-PC:~/Desktop$ pdsyw@pdsyw-PC:~/Desktop$ uname -aLinux pdsyw-PC 4.19.0-amd64-desktop #6034 SMP Thu Aug 17 14:31:55 CST 2023 x86_64 GNU/Linuxpdsyw@pdsyw-PC:~/Desktop$ 

2、查看python版本

pdsyw@pdsyw-PC:~/Desktop$ python --versionPython 2.7.16pdsyw@pdsyw-PC:~/Desktop$ pdsyw@pdsyw-PC:~/Desktop$ python3 --versionPython 3.7.3pdsyw@pdsyw-PC:~/Desktop$ 

3、安装pyenv依赖
