尝试在 centos 7 机器上安装 ruby 2.1.2，但遇到了 openssl 依赖问题
~ % ruby-install ruby
...blah blah blah...

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
!!! Installing dependencies failed!
疯狂的是，看起来我已经有了想要的包：
~ % yum list installed |grep ssl
openssl.x86_64 1:1.0.1e-34.el7_0.3 @updates
openssl-libs.x86_64 1:1.0.1e-34.el7_0.3 @updates
我该怎么做才能满足 SSL 依赖性？
接下来我尝试：
~ % yum install -y openssl-devel

错误信息非常模糊。
答案1
看着：
Package: 1:openssl-devel-1.0.1e-34.el7.x86_64 (base)
，我记得CentOS-Base.repo在设置我的盒子时修改了文件以包含其他镜像以及一些其他更改。不幸的是，我不确定是什么更改触发了错误。
我能够通过恢复/etc/yum.repos.d/CentOS-Base.repo到这里找到的文件来解决该问题：http://vault.centos.org/4.2/CentOS-Base.repo并运行yum install openssl
