• Mac 下安装Ruby环境


    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确。

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

    期间可能会问你sudo管理员password。这里可能须要等待一段时间后就能够安装成功好 RVM。

    案例信息例如以下:

    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

    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.

    Upgrade Notes:

      * No new notes to display.

    --这里就表示已经安装成功了--

    然后,加载 RVM 环境

        $ source ~/.rvm/scripts/rvm

    检查一下是否安装正确 :输入命令   rvm -v 。假设正确会列出RVM版本号 例如以下所看到的:

        $ 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

    相同继续等待漫长的下载,编译过程,完毕以后就安装好了。

    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 版本号

    RVM 装好以后,须要运行以下的命令将指定版本号的 Ruby 设置为系统默认版本号

        $ rvm 2.0.0 --default

    相同。也能够用其它版本号号。前提是你实用 rvm install 安装过那个版本号

    測试是否正确

     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
    
    
    这有可能是由于Ruby的默认源使用的是cocoapods.org。国内訪问这个网址有时候会有问题,网上的一种解决方式是将远替换成淘宝的。替换方式例如以下:
         $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,能够运行:

        $ 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。
