    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,这里可能需要等待一段时间后就可以成功安装好 RVM。

    案例信息如下:

    lihuifengdeMacBook-Pro:~ lihuifeng$ curl -L https://get.rvm.io | bash -s stable

      % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                  Dload  Upload   Total   Spent    Left  Speed 100   184  100   184    0     0      8      0  0:00:23  0:00:21  0:00:02     8 100 22817  100 22817    0     0    523      0  0:00:43  0:00:43 --:--:--  1056 Downloading https://github.com/wayneeseguin/rvm/archive/1.26.10.tar.gz Downloading https://github.com/wayneeseguin/rvm/releases/download/1.26.10/1.26.10.tar.gz.asc Found PGP signature at: 'https://github.com/wayneeseguin/rvm/releases/download/1.26.10/1.26.10.tar.gz.asc', but no GPG software exists to validate it, skipping. Upgrading the RVM installation in /Users/lihuifeng/.rvm/     RVM PATH line found in /Users/lihuifeng/.profile /Users/lihuifeng/.bashrc /Users/lihuifeng/.zshrc.     RVM sourcing line found in /Users/lihuifeng/.bash_profile /Users/lihuifeng/.zlogin. Upgrade of RVM in /Users/lihuifeng/.rvm/ is complete. # lihuifeng, # #   Thank you for using RVM! #   We sincerely hope that RVM helps to make your life easier and more enjoyable!!! # # ~Wayne, Michal & team.

    --这里就表示已经成功安装了--

    然后,载入 RVM 环境

        $ source ~/.rvm/scripts/rvm

    检查一下是否安装正确 :输入命令   rvm -v ,如果正确会列出RVM版本 如下所示:

        $ rvm -v A RVM version 1.26.10 (latest) is installed yet 1.25.28 (stable) is loaded. Please do one of the following:   * 'rvm reload'   * open a new shell   * 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.   * 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.

    步骤2 - 用 RVM 安装 Ruby 环境

      输入命令  $ rvm install 2.0.0

        $ rvm install 2.0.0

    同样继续等待漫长的下载,编译过程,完成以后就安装好了。

    A RVM version 1.26.10 (latest) is installed yet 1.25.28 (stable) is loaded. Please do one of the following:   * 'rvm reload'   * open a new shell   * 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.   * 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.

    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

    测试是否正确

     lihuifengdeMacBook-Pro:~ lihuifeng$ ruby -v ruby 2.0.0p481 (2014-05-08 revision 45883) [x86_64-darwin13.1.0] lihuifengdeMacBook-Pro:~ lihuifeng$ gem -v 2.2.2 这有可能是因为Ruby的默认源使用的是cocoapods.org,国内访问这个网址有时候会有问题,网上的一种解决方案是将远替换成淘宝的,替换方式如下:    $gem source -r https://rubygems.org/     $ gem source -a https://ruby.taobao.org lihuifengdeMacBook-Pro:~ lihuifeng$ gem source -r https://rubygems.org/ https://rubygems.org/ removed from sources lihuifengdeMacBook-Pro:~ lihuifeng$ gem source -a https://ruby.taobao.org https://ruby.taobao.org added to sources

     要想验证是否替换成功了,可以执行:

        $ gem sources -l  

    正常的输出结果:

    lihuifengdeMacBook-Pro:~ lihuifeng$ gem sources -l *** CURRENT SOURCES *** https://ruby.taobao.org

    这里就表示已经把Ruby环境成功的安装到了Mac 上了。
