在机架缓存中安装Ruby1.8.7-P374和Rails 3.2.13错误

Question

如何在Ruby1.8.7中安装Rails 3.2.13？

我的主机服务器使用这些版本，我希望使用CentOS 7框在Vagrant中设置一个环境。

我使用RVM安装了Ruby1.8.7。

当我试图安装Rails 3.2.13时，收到了一条错误消息：(rack-cache need ruby >= 2.0.0)

我是否知道如何使用Ruby1.8.7安装Rails 3.2.13？

[vagrant@ror02 ~]$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]
[vagrant@ror02 ~]$ gem install rails -v 3.2.13

如果您有rvm，您可以只安装最新的ruby和rails。没有必要使用系统宽安装版本。

我只使用ruby 2.5.1和rails 5.2.0。
