我认为您正在寻找的是 ruby 版本管理器 (rvm)。它在此处可用,并允许您管理 Ruby、Rails 和 Gem 集的版本。
https://rvm.io/
这里也有一个很好的入门指南:http ://rvm.beginrescueend.com/rvm/install/
以下是安装过程:
[sam@mungr ~]$ \curl -L https://get.rvm.io | bash -s stable --ruby

完成后,我已经安装了 Ruby 1.9.3-p362 的全功能安装:
[sam@mungr ~]$ source /home/sam/.rvm/scripts/rvm
[sam@mungr ~]$ rvm list
rvm rubies
=* ruby-1.9.3-p362 [ x86_64 ]
# => - current
# =* - current && default
# * - default
哪个版本的 Ruby?
[sam@mungr ~]$ which ruby
~/.rvm/rubies/ruby-1.9.3-p362/bin/ruby
一个小小的Hello World
[sam@mungr ~]$ ruby -e "puts 'Hello world'"

在讨论这个问题的过程中,作者Crivens指出他遇到了以下错误:
错误 curl: (77) SSL CA 证书有问题(路径?访问权限?)并且操作系统是 Linux 版本 2.6.32-042stab055.16 (root@rh6-build-x64) (gcc 版本 4.4.4 20100726 (Red Hat) 4.4.4-13) (GCC) ) #1 SMP Fri Jun 8 19:22:28 MSD 2012. 我仍然希望使用 ruby 的系统安装。
如果您遇到此错误,通常意味着以下两种情况之一:
1.我认为您只是缺少此 RPM,ca-certificates-2010.63-3.el6。这些是证书。我在 Ubuntu 8.04.4 机器上安装 RVM 失败。我应该将它安装为多用户吗?
解决方案#1
% yum install ca-certificates-2010.63-3.el6
2. rvm 的开发者 Wayne 将 URL 从 rvm.beginrescueend.com 更改为 rvm.io,并且可能会弄乱 SSL 证书。使用 RVM 安装 Ruby 1.9.2 时出现 Curl 证书错误
解决方案#2
% curl -L get.rvm.io | bash -s stable
-or-
% echo insecure > ~/.curlrc
