Multilib version problems found. This often means that the root...

腾讯云安装nginx，然后到安装pcre依赖的时候报了这个错，谷歌了一下，报这个错一般意味着：

1、 You have an upgrade for pcre which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of pcre 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 pcre.otherarch … this should give you an error
message showing the root cause of the problem.

2、 You have multiple architectures of pcre installed, but
yum can only see an upgrade for one of those architectures.
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 pcre installed already.
You can use “yum check” to get yum show these errors.

。。。。。。

解决：

我的情况应该是pcre包重复了。然后，我用

#rpm -qa | grep pcre

查看pcre是否重复，安装，果然有，然后我用

#yum remove 其中一个的pcre的包名       //卸载

再重新安装：

# yum install -y pcre pcre-devel

搞定！
