生成脚手架Micropost的错误

Question

我正在关注http://ruby.railstutorial.org/从我的应用程序目录中运行此命令但收到下面的错误。我已经搜索过，但可以找出如何解决。

$ 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

的关键是在错误消息的第一行。

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

然后在你的路由文件，你有那些时间，不属于通知。

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

删除句点。

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