解决multilib版本问题

我使用Centos 6.4

当我尝试安装libgcc与yum install libgcc.i686我采取了以下按摩。

 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 libgcc which is missing some dependency that another package requires. Yum is trying to solve this by installing an older version of libgcc 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 libgcc.otherarch ... this should give you an error message showing the root cause of the problem. 2. You have multiple architectures of libgcc 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 libgcc 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: libgcc-4.4.7-4.el6.i686 != libgcc-4.4.7-3.el6.x86_64 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles –nodigest 

我如何安装libgcc.i686？

• 为什么我不能在Ubuntu 14.04 32bit上安装mongodb 3.0？
• 为什么Debian 6.0.1在安装东西时要求安装CD？
• 在没有安装CD的情况下在Win Server 2003上安装IIS？
• GPO安装 – 区分64位和32位系统
• 如何在不更新存储库信息的情况下安装yum软件包？

 yum install libgcc.x86_64 libgcc.i686
