我在 BlueHost 上有一个 VPS 帐户。操作系统是 CentOS6.7 x86_64，PHP 版本是 5.4.28。我按照以下说明操作这里安装XCache，安装失败。启用EPEL仓库后，安装再次失败。以下是安装命令和错误消息。
yum 安装 php-xcache xcache-admin
Loaded plugins: fastestmirror, security

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我觉得 EPEL 不是合适的软件包。但我还应该使用什么？请帮我解决这个问题。谢谢！
