生成Scaffold Micropost时出错

Question

我按照应用程序目录中的http://ruby.railstutorial.org/运行此命令，但收到下面的错误。我已经到处找过了，但还是想出了解决办法。

$ rails generate scaffold Micropost content:string user_id:integer

这是错误：

我的routes.rb是：

DemoApp::Application.routes.draw do
  resources :users
  .
  .
  .
end

Answer 1

关键字在错误消息的第一行。

/config/routes.rb:4: syntax error, unexpected '.' (SyntaxError)

然后在你的路径文件中，注意你有那些不属于的句号。

DemoApp::Application.routes.draw do
  resources :users
  .
  .
  .
end

删除句点。

DemoApp::Application.routes.draw do
  resources :users
end
