我正在尝试运行命令：ruby script/rails server webrick -e production
它吐出这个错误：

我已经安装了 activerecord-mysql-adapter - 它没有错误......
我试图更改 Gemfile 以匹配它吐出的错误，即 (~> 2.8.1) 版本，但这也不起作用......
任何帮助将不胜感激...
更新！！
我卸载了 MySQL 2.9.0 并安装了 MySQL 2.8.1 并更改了我的 Gemfile 以反映正确的版本，但现在我收到了这个错误：
=> Booting WEBrick
=> Rails 3.2.8 application starting in production on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
