要求：perl(Compress::Raw::Zlib) = 2.052

Question

我试图运行yum update但被依赖项阻止。我已经安装了其他软件包所需的 rpmforge el6。

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

Answer 1

1:已安装软件包上的软件包名称之前的名称意味着它的纪元为1。可用软件包上没有此符号意味着它们的纪元为 0。较高的纪元值将胜过较高的版本和发行版值，因此您可以选择必须降级到 0:2.052 并固定软件包版本，否则 RPMForge 将不得不通过将纪元更改为 1 并重建来修复其软件包。
