CentOS 7自带了ruby 2.0.0.353-20.el7。 我试图在那里安装木偶，并且遇到错误。 首先我运行：
rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm rpm -ivh http://dl.fedoraproject.org/pub/epel/beta/7/x86_64/epel-release-7-1.noarch.rpm 那些工作很好。 然后我遇到了这个问题：

它看起来需要ruby1.8。 Ruby 2.0默认安装，看起来是最早可用的。 我错过了什么？
看来你已经安装了EL6的puppetlabs回购，然后删除，并用EL7的回购replace。 但是yum仍然有EL6回购的caching数据。 只是清理出来，然后再试一次。
yum clean all
