Ruby on Rails服务器将无法运行

当我尝试启动应用程序时，为什么我的服务器没有运行？我安装了node.js，我相信我也安装了execjs，这既没有解决问题。不知道问题是什么。是的我是新人，所以请给我一些松懈！感谢

FirstApp？我想你正在参加Hartl的教程。你是怎么安装rails的？

如果你通过rails安装程序安装了windows，可能你的版本高于4.0.8而你在Gemfile中手动切换版本，这种情况并不好。如果是这种情况，请从头开始安装4.0.8并使用它创建firstapp。的 [1]

开发的语法更改很少.rb，我认为即使你在那里手动更改文本它也行不通。您可以尝试将Rails.application.configure.do更改为FirstApp::Application.configure.do

请告诉我怎么回事。当您提供更多信息时，我会尝试更新我的答案。

$ rails -v
$ gem uninstall rails --version VERSION
$ gem install rails --version VERSION
