Ruby on rails Rvm安装ruby-2.4.1

我以前用ruby和rails下载过rvm，但它带来了一个我无法解决的问题，所以我使用了gems并在rvm中内爆，但现在我要求安装ruby，它没有，当我给它一个ruby-v时，它似乎已经安装，版本2.4.1，同样的情况也发生在版本4.2.6中的rails上。我做什么？发生了什么事

我通过更改rails的版本避开了这个问题，如下所示：

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', github: 'rails/rails', branch: '4-2-stable'

我解决了这个错误，我将

gem'openssl'，2.0.4'

放在gem文件中，但现在更改了错误，root@ubuntu：~/teste#rails s=>启动WEBrick=>rails 4.2.6应用程序在上开始开发=>运行
