我有 CentOS 6.5
我正在尝试通过 yum 安装 git，但是在安装先决条件包时出现错误。我不需要，但是使用 root 运行 sudo 也不会有什么坏处。
错误信息：
--> Finished Dependency Resolution
Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:
1. You have an upgrade for libselinux which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libselinux of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude libselinux.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libselinux installed, but
yum can only see an upgrade for one of those arcitectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.
3. You have duplicate versions of libselinux installed already.
You can use "yum check" to get yum show these errors.
...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).
Protected multilib versions: libselinux-2.0.94-5.3.el6_4.1.i686 != libselinux-2.0.94-5.8.el6.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

现在yum 重新排序显示额外的一行（用于额外的软件包 - CentOS）：
epel Extra Packages for Enterprise Linux 6 - x86_64 11,838
仍在运行： sudo yum -y 安装 curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker仍然给我同样的错误（正如上面提到的，我首先遇到的）。

Puppetlabs.repo 对于这篇文章来说似乎是多余的，在我下载并安装了额外的包 repo rpm（如上面的帖子/链接所列）后，前 2 个 .repo 文件安装在这里，而 mycompany.redhat.repo 中的内容是：
[release.update]

感谢 Michael H。我在 /etc/yum.repos.d/CentOS-Base.repo 创建了一个文件（我将其稍微通用化，以便它可以适用于任何 6.x 或 7 版本）。它在 6.5 上工作正常。如果您在 CentOS 7.x 上使用此文件时发现任何问题，那么您只需要正确的 CentOS-Base.repo（CentOS 7.x 或任何 XY 版本的官方 .repo 文件），帖子中的问题就会得到解决。
/etc/yum.repos.d/CentOS-Base-Custom.repo 的内容 （附言：我将其命名为自定义，因为我没有使用硬编码版本 6，而是使用了$发布版本变量名称、镜像列表、baseurl、gpgkey.repo 文件内的字段。
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

冉:sudo yum -y 安装 curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker并且它没有任何错误地运行。
重新运行相同程序，输出符合预期。

我现在需要的只是使用 Ansible 中的模板模块（并在目标机器上的 /etc/yum.repos.d 文件夹中设置此文件），完成后，上述先决条件将被安装而不会出现任何错误，并且 ansible 将安装我需要的（用户定义的 GIT 版本）。
