yum报错：Error: Multilib version problems found. This often means that the root

使用yum安装一些依赖库报错：

yum -y install gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

错误信息
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 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.

...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: pcre-8.32-17.el7.x86_64 != pcre-8.32-15.el7_2.1.i686

报错原因：重复安装依赖库
rpm -q pcre-8.32-15.el7_2.1.i686 (查看是否已安装相关库)

修复方法：删除已安装的依赖库（由于是新环境，所以可以删除，线上环境可以尝试使用update）

rpm -e   pcre-8.32-15.el7_2.1.i686

再次使用yum安装成功
