安装 RVM 和 Ruby

更新 apt，并安装 curl：

$ sudo apt-get update
$ sudo apt-get install curl

然后安装 RVM：

$ \curl -sSL https://get.rvm.io | bash

步骤1 － 安装 RVM

RVM 是干什么的这里就不解释了，后面你将会慢慢搞明白。

$ curl -L https://get.rvm.io | bash -s stable

期间可能会问你sudo管理员密码，以及自动通过homebrew安装依赖包，等待一段时间后就可以成功安装好 RVM。

然后，载入 RVM 环境（新开 Termal 就不用这么做了，会自动重新载入的）

$ source ~/.rvm/scripts/rvm

检查一下是否安装正确

$ rvm -v
rvm 1.22.17 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

步骤2 － 用 RVM 安装 Ruby 环境

$ rvm install 2.0.0

同样继续等待漫长的下载，编译过程，完成以后，Ruby, Ruby Gems 就安装好了。

步骤3 － 设置 Ruby 版本

RVM 装好以后，需要执行下面的命令将指定版本的 Ruby 设置为系统默认版本

$ rvm 2.0.0 --default

同样，也可以用其他版本号，前提是你有用 rvm install 安装过那个版本

这个时候你可以测试是否正确

$ ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin13.0.0]

$ gem -v
2.1.6

$ gem source -r https://rubygems.org/
$ gem source -a https://ruby.taobao.org

步骤4 － 安装 Rails 环境

上面 3 个步骤过后，Ruby 环境就安装好了，接下来安装 Rails

$ gem install rails

然后测试安装是否正确

$ rails -v
Rails 3.2.13

---

然后开始你的 Ruby，Rails 之旅吧。
欢迎来到 Ruby 的世界！

actually after installation of rvm , you have to run the script. i was stuck in the same level as you are, than in terminal i read this line: " To start using RVM you need to run source /usr/local/rvm/scripts/rvm "  so place this command (source /usr/local/rvm/scripts/rvm) in terminal and enter and after that : type rvm | head -1 rvm is a function (this you will see hopefully)

如果重启等再遇到  No command 'rvm' found, but there are 20 similar ones

source /usr/local/rvm/scripts/rvm

type rvm | head -1
rvm is a function (this you will see hopefully)

source /usr/local/rvm/scripts/rvm

rvm 2.0.0 --default
