管理平台安装用ActiveRecord-mysql的适配器

Question

我正在一个CentOS 6.3 Linux服务器和Ruby版本上：1.8.7和创业板的版本：25年8月1日

我试图运行命令： ruby script/rails server webrick -e production

它吐出了这个错误：

=> 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

我已经安装了activerecord-mysql-adapter - 它没有错误...

我试着改变Gemfile以匹配它吐出的错误（〜> 2.8.1）版本，但是没有工作要么...

任何帮助真的会感激...

更新！

我卸载的MySQL 2.9.0和安装了MySQL 2.8.1和改变了我的Gemfile以反映正确的版本，但现在我得到这个错误：

编辑：我想通了.. 。我需要运行命令：RAILS_ENV=production bundle exec rake db:migrate

DOH！

Answer 1

尝试

bundle exec ruby script/rails server webrick -e production 

而且，你为什么要使用脚本/导轨上？这应该工作：

bundle exec rails server webrick -e production
