我正在尝试安装软件包，但当我将它们放在镜像中时，我无法使用 yum install 找到它们。
这是我的 /etc/yum.repos.d/CentOS-OpenShift-Origin36.repo 的内容：

如果我们照镜子http://mirror.centos.org/centos/7/paas/x86_64/openshift-origin36/我们可以看到origin-node就在那里。但是当我这样做时：
yum install origin-node
我无法安装它...
我该怎么做？我也想安装这个版本 origin-node-3.6.0-1.0.c4dd4cf.x86_64.rpm> 我该如何指定它？
谢谢
编辑1：
我跑：
yum clean all
并得到：
Loaded plugins: fastestmirror
Cleaning repos: base centos-openshift-origin36 epel extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors
然后我做了：
yum update
但仍然是同样的错误。
