编辑：感谢所有你的帮助家伙:),终于弄清楚了.这是我做过的sparknotes版本：

(如果你不熟悉命令行,http://jewelrybox.unfiniti.com/是一个天赐).

>安装RVM(https://rvm.beginrescueend.com/)
它同时在一个comp(mac / linux only)上管理多个版本的Ruby.使文件夹的不同版本的Ruby可以独立工作(从我所了解的).
>获取XCode(https://developer.apple.com/xcode/)
需要一起编译代码.但是,您还需要gcc,它不会与最新版本的XCode一起打包.洙….
>在这里(https://developer.apple.com/downloads/index.action)并下载“XCode的命令行工具”简单直接运行.
>安装Macports(http://www.macports.org/install.PHP),以便我可以…
>通过终端安装make(port install make).不知道它是做什么的,但终端在安装之前给出了错误,之后没有错误.

现在我们准备好了:)

run(rvm install 1.9.3)
出去一会儿需要一段时间

然后(rvm 1.9.3 – 默认)

然后(gem安装rails)
要安装Ruby on Rails.这也需要一段时间.

一旦我设置了rails 3,我做了一个测试应用程序.
(rails new tester) – 构建目录
(cd测试仪) – 移动到新的目录

(rails server)设置服务器

然后,在互联网上跳转(http：// localhost：3000).如果一切顺利,您应该在浏览器中看到欢迎到rails.
