推荐答案
"rvm"工具非常好.我认为它代表Ruby Verson Manager，并且开发人员擅长在irc渠道中提供支持.您可以并排安装多个版本的红宝石，选择要使用的版本.
The tool "rvm" is pretty good. It stands for Ruby Verson Manager I think, and the developer is good at support in the irc channels. You can install multiple versions of ruby along side each other pick the ones you want to use.
