apt (Debian or Ubuntu)

Debian GNU/Linux and Ubuntu use the apt package manager. You can use it like this:

$ sudo apt-get install ruby-full

As of writing, the ruby-full package provides Ruby 1.9.3, which is an old stable release, on Debian and Ubuntu.

可能会遇到这样的情况：你只要更新一下 apt-get update ,在进行安装就可以了

安装完成后：

可以输入：ruby -v进行验证
