如出现类似上面的依赖问题，解决方法目前我知道有三种
1.使用package-cleanup --dupes && package-cleanup --problems命令（无效的话尝试下面方法）
若提示#package-cleanup: command not found
请执行yum install yum-utils.noarch
2.启用该源安装 yum install --enablerepo=webtatic 需要安装的软件包名 （建议使用）
3.或者yum remove 依赖包（谨慎使用）
删除依赖包的时候会同时删除依赖于它的软件包，所以删除依赖包后需要重新安装这些软件包（包括依赖包）。一定谨慎使用。
