推荐答案

您使用的是 RVM 而不是 10.8 附带的 Ruby.好的.现在，停止使用 10.8 附带的 MySQL.

You're using RVM instead of the Ruby that comes with 10.8. Good. Now, stop using the MySQL that comes with 10.8.

安装和更新 Homebrew.现在运行

Install and update Homebrew. Now run

brew install mysql

在您的项目中使用 /Gemfile 来安装 mysql2 gem.添加

Use the /Gemfile in your project to install the mysql2 gem. Add

gem "mysql2"

到你的 /Gemfile.然后通过运行使用 Bundler 更新您的应用程序

to your /Gemfile. Then update your application with Bundler by running

bundle install

让包管理器(Homebrew 和 Bundler) 为你工作.

Let the package managers (Homebrew and Bundler) work for you.

这应该可以解决您遇到的问题.

This should fix the issues you're having.
