在CentOS中，执行 yum update 命令一直提示 libpcre太旧

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
执行yum remove pcre 又会提示 yum是依赖关系，受保护，不能remove
--> Finished Dependency Resolution
Error: Trying to remove "yum", which is protected
只好执行强制移除命令，忽略依赖关系
[root@ycga local]# rpm -e --nodeps pcre
再次重新安装
[root@ycga local]# yum install -y pcre pcre-devel
安装成功
[root@ycga local]# yum install -y pcre pcre-devel
