当执行以下命令安装依赖时候:yum -y install libaio.so.1 libgcc_s.so.1 libstdc++.so.6时候出现了如下错误:Loaded plugins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * extras: centos.ustc.edu.cn * updates: mirrors.cn99.comSetting up Install ProcessResolving Dependencies--> Running transaction check---> Package libaio.i686 0:0.3.107-10.el6 will be installed---> Package libgcc.i686 0:4.4.7-23.el6 will be installed---> Package libstdc++.i686 0:4.4.7-23.el6 will be installed--> Finished Dependency ResolutionError: 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).
