解決多庫版本問題

我使用CentOS 6.4

當我嘗試安裝 libgcc 時，yum install libgcc.i686我做了以下按摩。

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

我該如何安裝libgcc.i686？

您的版本似乎與您嘗試安裝libgcc.x86_64的版本不同（ vs. ）。嘗試在安裝 i686-lib 的同時更新 x86_64 lib：libgcc.i686``4.4.7-3``4.4.7-4

yum install libgcc.x86_64 libgcc.i686

我在打斷後yum update（在我的情況下是在 ansible 執行期間）遇到了這個問題。閱讀此執行緒後，我最終將其修復為：

package-cleanup --cleandupes

雖然在此之前我也嘗試過按照@etagenklo 的建議執行命令，並且還嘗試過：

yum-complete-transaction
yum-complete-transaction --cleanup-only
yum check                # report generally
package-cleanup --dupes  # report on duplicate packages in particular
