求助！CentOS 6.5安装桌面环境不成功！

在阿里云安装桌面环境，使用以下命令安装图形化界面。但是出现报错，在虚拟机同样为CentOS 6.5没有任何问题。看报错信息好像是说当前已安装的rpm包版本太高。
搞不明白为什么阿里云安装的这些rpm包是这样的。
比如下载的centos6.5里glibc-common = 2.12-1.132.el6，但是阿里云却是glibc-common-2.12-1.166.el6_7.7.x86_64 (@updates)



yum -y groupinstall Desktop
yum -y groupinstall "X Window System"

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
