我正在尝试在运行 OS X 10.8 的新 Macbook Air 上设置我的 Rails 应用程序（在 Debian 服务器上运行良好）。
我从安装 homebrew 和 rvm 开始，我使用 rvm 安装了 ruby 1.9.3，使用gem install rails. 到目前为止效果很好。然后我从我的 svn repo 下载了我的 rails 应用程序并运行rails new myapp它添加了不受版本控制的额外文件（例如数据库配置等）。捆绑安装运行良好。
但是当我尝试启动服务器时，我得到了这个：
$ rails server

我正在运行 rails 4.0，我的 Gemfile 看起来像这样：
