每次我尝试#sudo yum update 时，我都会收到 PyYAML-3.08-4.el5.x86_64 缺少依赖项 libyaml-0.so.1()(64bit) 的警告。

所以我做了一些检查，似乎确实安装了 libyaml，所以我想知道我的 PyYAML 和 libyaml 安装有什么问题。libyaml 是由 PyYAML 自动提取的，这让我认为 repo 发生了一些奇怪的事情。YUM 的输出如下：

[root@am-web-1 ~]# yum update

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

所以我们知道我们有问题，那么这个 libyaml 到底在哪里？

那么图书馆存在吗？

[alexander@am-web-1 ~]$ ls /usr/lib64/libyaml-0.so.1*
/usr/lib64/libyaml-0.so.1  /usr/lib64/libyaml-0.so.1.1.0

64位的可以，32位的可以吗？

[alexander@am-web-1 ~]$ ls /usr/lib/libyaml-0.so.1*
/usr/lib/libyaml-0.so.1  /usr/lib/libyaml-0.so.1.1.0

它们都存在，那有什么问题？！？

这更像是一个ServerFault问题，但我在更新/安装 Cobbler 时看到了同样的问题。这是您此时启用的多个存储库的问题。同时永久启用两个存储库通常是不好的做法。libyaml来自RPMForge的包和通过EPEL存储库提供的包之间存在轻微冲突。

要修复，请通过 删除 RPMForge 包yum erase libyaml，然后使用 继续更新yum update --disablerepo=rpmforge。您还可以通过从 RPMForge 存储库配置文件中永久排除该特定包来采取额外的步骤...

受@ewwhite 的回答启发，我发现这样做效果很好

yum erase libyaml
yum install --disablerepo=rpmforge libyaml-devel
