我正在尝试跑步rails server，但我看到了这样的事情：

C:\Users\Mama  i Tata>cd  c:/rails_project/my_app

我正在使用 Ruby 1.9.3p194 (2012-04-20) [i386-mingw32]。

有什么想法吗？

根据第 5 章中的调试日志和 Rails 教程，我了解您尝试复制和粘贴路由文件：

SampleApp::Application.routes.draw do
  get "static_pages/home"
  .......
end

SampleApp这里代表应用程序的名称，从您的目录名称中我认为应该是MyApp.

您的路线文件应该是：

MyApp::Application.routes.draw do
  get "static_pages/home"
  .......
end

这只是一个初步的猜测。
