我一直在关注一些指南，将一个相当宝石重的系统从Rails 2.3.5升级到Rails 3.2.17。虽然升级到Rails后我遇到的大多数问题都是关于升级ActiveRecord调用，或者安装或升级Gem，但是当我运行“ bundle exec rails s 时，我完全被以下堆栈跟踪困扰了strong>“启动服务器：
$ bundle exec rails s
=> Booting Thin
=> Rails 3.2.12 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
