使用CocoaPods时提示安装高版本ruby遇到的坑。

安装的那些基本方法不再赘述，请对坑填坑。

当pod install 时提示：

RubyGems installed the following executables:

/Users/sharktop/.rvm/rubies/ruby-2.3.0/bin/gem

Ruby Interactive (ri) documentation was installed. ri is kind of like man 

pages for ruby libraries. You may access it like this:

  ri Classname

  ri Classname.class_method

  ri Classname#instance_method

If you do not wish to install this documentation in the future, use the

--no-document flag, or set it as the default in your ~/.gemrc file. See

'gem help env' for details.
