python-3.6 - 在 rhel7 上安装 python36-devel 失败

Question

尝试在 RHEL7 上安装 python36-devel，最终出现错误

尝试解决错误中所述的依赖关系，但没有帮助。

也试过这个 How to install python3-devel on red hat 7 ，这也以同样的错误告终
yum install python36-devel
错误:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

yum除非你明确告诉他，否则他不喜欢降级软件包。
python36-devel需要 python36-libs具有完全相同的版本号。但是您有 python36-libs安装了 更高 版本号。您有两个选择:

找出原因 yum只能找到旧版本的 python36-devel ，从逻辑上讲，您应该能够找到 python36-devel-3.6.8-10在您安装 python36-libs 的同一存储库中来自(@rhui-REGION-rhel-server-releases)。

降级python36-libs到与 python36-devel 相同的版本您正在尝试安装。

降级安装 python36-devel :

yum downgrade python36-libs-3.6.8-1.el7.x86_64
yum install python36-devel

甚至在一个单一的操作可能工作:

yum swap -- downgrade python36-libs-3.6.8-1.el7.x86_64 -- install python36-devel
