尝试在RHEL7上安装python36-devel，最终会收到错误消息

尝试按照错误所述解决依赖关系，但没有帮助。

也尝试过此How to install python3-devel on red hat 7，它也以相同的错误结束

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

Answer 1

yum不喜欢降级软件包，除非您明确告诉他这样做。

python36-devel要求python36-libs具有完全相同的版本号。但是，您python36-libs安装了更高版本号。您有两种选择：

找出为什么yum只能找到旧版本的python36-devel，从逻辑上讲，您应该能够在安装python36-devel-3.6.8-10的同一存储库中找到python36-libs， @ rhui-REGION-rhel-server-releases。
将python36-libs降级为与您要安装的python36-devel相同的版本。

要降级并安装python36-devel：

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

或什至只执行一项操作：

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

截至2019年8月23日，我发现以下解决方法可处理ol7_developer_EPEL存储库中的python36-3.6.8-1，落后于ol7_latest中的python36-3.6.8-10。

显然，仓库 @ rhui-REGION-rhel-server-releases 具有python3-libs-3.6.8-10.el7.x86_64，但没有较低版本的 python36-libs- 3.6.8-1.el7.x86_64 。

Chris Maes指出，python36-devel和python36-libs应该具有完全相同的版本。

epel 存储库具有相同版本的两个库，但是由于与 @ rhui-REGION-rhel-server-releases 冲突，安装已升级。 / p>

因此，禁用仓库 @ rhui-REGION-rhel-server-releases ，并对两个库使用 epel

sudo yum-config-manager --disable rhui-REGION-rhel-server-releases
sudo yum-config-manager --disable @rhui-REGION-rhel-server-releases
sudo yum install python36-setuptools -y 
sudo yum install python36-devel -y 
# enable later
sudo yum-config-manager --enable rhui-REGION-rhel-server-releases
sudo yum-config-manager --enable @rhui-REGION-rhel-server-releases
