如果打印：

…  ruby-2.2.2 - #validate archive
        ruby-2.2.2 - #extract
        ruby-2.2.2 - #validate binary
        ruby-2.2.2 - #setup
        ruby-2.2.2 - #gemset created /Users/abc/.rvm/gems/ruby-2.2.2@global
        ruby-2.2.2 - #importing gemset             
       /Users/abc/.rvm/gemsets/global.gems..............................
        ruby-2.2.2 - #generating global wrappers........
        ruby-2.2.2 - #gemset created /Users/abc/.rvm/gems/ruby-2.2.2
        ruby-2.2.2 - #importing gemsetfile /Users/abc/.rvm/gemsets/default.gems                          
     　　evaluated to empty gem list 
        ruby-2.2.2 - #generating default wrappers........
        Updating certificates in '/etc/openssl/cert.pem'.
        mkdir: /etc/openssl: Permission denied
        mkdir -p "/etc/openssl" failed, retrying with sudo
        LiuWenqiang password required for 'mkdir -p /etc/openssl': 
        and sudo mkdir worked

则说明安装成功了  
 打印代码：

Done with Command Line Tools (OS X 10.11) for Xcode
    Done.
    ==> /usr/bin/sudo /bin/rm -f /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress ==> Installing the Command Line Tools (expect a GUI popup): ==> /usr/bin/sudo /usr/bin/xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates
    Failed during: /usr/bin/sudo /usr/bin/xcode-select --install
    Requirements installation failed with status: 1.

则失败。  
如果安装失败，解决方案：  
$ sudo xcode-select –switch /Library/Developer/CommandLineTools/

Password: （输入电脑权限密码）

$ git

usage: git [--version] [--help] [-C <path>] [-c name=value]
    
    [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
    
    [-p | --paginate | --no-pager] [--no-replace-objects] [--bare]
    
    [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
    
    <command> [<args>]

第二个问题就解决了  
然后再重新执行：安装2.2.2版本 步骤 就可以解决
