mysql2 gem与mysql 5.6.19不兼容

我想在mac osx 10.9.3上运行rails应用程序，但出现以下错误：

/Users/home/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/mysql2-0.3.16/lib/mysql2.rb:8:in `require': Incorrect MySQL client library version! This gem was compiled for 5.5.23 but the client library is 5.6.19. (RuntimeError)

这是我的database.yml文件

development:
  adapter: mysql2
  encoding: utf8
  database: simple_cms_development
  pool: 5
  username: root
  password: somepassword
  socket: /tmp/mysql.sock

test:
  adapter: mysql2
  encoding: utf8
  database: simple_cms_test
  pool: 5
  username: root
  password: somepassword
  socket: /tmp/mysql.sock

production:
  adapter: mysql2
  encoding: utf8
  database: simple_cms_production
  pool: 5
  username: root
  password: somepassword
  socket: /tmp/mysql.sock

如何解决它？

标题

我打算建议使用mysql C-connector，评论中的推荐答案证实了这一点

我们已经为典型的无法构建本机扩展错误写了一篇关于如何做到这一点的文章，但想法相同

C型连接器

基本上，您的gem只需要与您的系统接口；它不需要做任何事情，只需发送查询和处理对数据库的响应

这意味着，如果您的mysql版本的兼容性有问题，最好为您的gem安装一批单独的头文件：

实现这一点的方法是——重要的是——获得您可以使用的32位版本 安装程序或解压缩文件

安装后，应使用以下命令安装gem：

gem安装mysql2-platform=ruby - ‘-使用mysql dir=YOUR_mysql_dir“'

---

这将为您安装gem，这将允许您与MYSQL服务器接口

我可以用Brew安装它吗？嗯-有错误吗？你的MYSQL服务器是本地安装的吗？我也有同样的问题。我添加了dev.mysql.com上提供的apt-get存储库：。请确保您计算机上的所有mysql软件mysql客户端、mysql服务器、mysql实用程序、libmysqlclient18等都已使用此存储库安装和更新。然后我运行了sudo apt get install libmysqlclient-dev。之后，我成功地在mac os x上安装了mysql2 gem.sudo apt get install libmysqlclient dev！！！！
