### 安装 RVM ###

RVM (Ruby enVironment Manager)是一个命令行工具，可以提供一个便捷的多版本 Ruby 环境的管理和切换。

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

执行后，大概输出如下：

% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                     Dload  Upload   Total   Spent    Left  Speed
    100   194  100   194    0     0     91      0  0:00:02  0:00:02 --:--:--    91

    Installing RVM to /Users/x x x/.rvm/
        Adding rvm PATH line to /Users/username/.profile /Users/username/.mkshrc /Users/username/.bashrc /Users/username/.zshrc.
    /Users/username/.rvm/src/rvm/scripts/functions/installer: line 1103: /Users/username/.zshrc: Is a directory
        Adding rvm loading line to /Users/username/.profile /Users/username/.bash_profile /Users/username/.zlogin.
    Installation of RVM in /Users/username/.rvm/ is almost complete:
    
      * To start using RVM you need to run `source /Users/username/.rvm/scripts/rvm`
        in all your open shell windows, in rare cases you need to reopen all shell windows.
    Thanks for installing RVM ?

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

类似输出：

rvm 1.29.12 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]
