感谢您的帮助。
 
解决方案
您使用RVM而不是10.8版本的Ruby。好。现在，停止使用10.8附带的MySQL。 
 
 
 
安装并更新  。现在运行 
 
 
  brew install mysql 
  
使用项目中的 / Gemfile 来安装 mysql2  gem。添加
  gemmysql2
  
添加到 / Gemfile 中。然后通过运行来更新您的应用程序Bundle 
 
 
  bundle install 
  
让包管理器（Homebrew和Bundler）为您工作。 
 
 
解决您遇到的问题。

Thanks for your help.
 解决方案 
You're using RVM instead of the Ruby that comes with 10.8. Good. Now, stop using the MySQL that comes with 10.8. 
Install and update Homebrew. Now run
brew install mysql
Use the /Gemfile in your project to install the mysql2 gem. Add
gem "mysql2"
to your /Gemfile. Then update your application with Bundler by running
bundle install
Let the package managers (Homebrew and Bundler) work for you.
This should fix the issues you're having.
