我正在尝试解决一个依赖关系。由于 RHEL6 不包含 python-2.4.3，因此我从 RHEL5 下载了该软件包并将其放入我们自己的存储库中。然后在安装它时：
...

---> Package mx.x86_64 0:2.0.6-2.2.2 will be installed

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
因此我尝试手动安装。
[root@render3 dusan]# yum install python-2.4.3

我该如何解决这个问题？
答案1
解决方案是重建 RHEL 6 的专有软件包，以便它使用 RHEL 6 附带的 Python 版本（和其他依赖项）。尝试强制它使用旧的 Python 版本并不是正确的方法。
答案2
您可以根据当前的 CentOS 6 设置从源代码创建自己的 RPM。
如何做到这一点的简短答案是
rpmbuild --rebuild /tmp/mypythonpackagename-2.3.4-56.src.rpm
答案3
您正在尝试安装较旧的 Python 版本来替换较新的版本。由于 yum 依赖于 Python，因此这不是一个好主意。
使用类似以下存储库同时安装旧版 Python 版本这个
