我将不胜感激安装Ruby 1.9.3-p374在Mountain Lion OS X.
我是 ruby 新手，目前正在尝试从 1.8.7 升级，但每当我输入rvm install 1.9.3-p374命令行时，我都会得到：
user-macbook-pro-2:~ user$ rvm install 1.9.3-p374
No binary rubies available for: downloads/ruby-1.9.3-p374.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

任何有关如何解决此问题的帮助将不胜感激。错误部分重复如下：
