我正在尝试php-mcrypt为我的 CentOs 6.4 服务器安装扩展，但是它失败并显示以下消息：
[root@vps /]# yum install php-mcrypt

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
据我所知，我已经正确安装了 repos，这是我的 epel.repo 文件：
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
我的回复者：
repo id repo name status
base CentOS-6 - Base 4,802
epel Extra Packages for Enterprise Linux 6 - i386 5,931
epel-debuginfo Extra Packages for Enterprise Linux 6 - i386 - Debug 1,816
epel-source Extra Packages for Enterprise Linux 6 - i386 - Source 0
extras CentOS-6 - Extras 12
updates CentOS-6 - Updates 481
repolist: 13,042
我甚至安装了 remi，但似乎无法为 ZF2 安装 php-mcrypt 扩展。出于某种原因，它似乎正在从 repo 中提取，el5尽管我的所有 repo 都是el6？
有人知道发生了什么事吗？
谢谢
弥敦道
