yum 安装 出错 Error: Protected multilib versions:

例如：安装zlib出错

yum install zlib-1.2.3-29.el6.i686

Error: Protected multilib versions: zlib-1.2.3-29.el6.i686 != zlib-1.2.3-27.el6.x86_64
?You could try using --skip-broken to work around the problem
?You could try running: rpm -Va --nofiles --nodigest

?

原因：多个库共存冲突

?

解决办法：在执行命令后面加上：--setopt=protected_multilib=false?

?

再次执行：yum install zlib-1.2.3-29.el6.i686 ?--setopt=protected_multilib=false?
