ActionController :: RoutingError(没有路由与[GET]"/"匹配): [英] ActionController::RoutingError (No route matches [GET] "/"):

问题描述

我正在玩一个使用独角兽和护栏的教程.我对Rails完全陌生，对于本教程而言，我为该项目所做的所有操作都是bundle exec rails new rails-starter，而无需进行进一步的应用程序修改.

I'm playing around with a tutorial which uses unicorn and rails. I'm completely new to rails and for the purpose of the tutorial all I've done for the project is bundle exec rails new rails-starter with no further app modifications.

运行bundle exec unicorn -c config/unicorn.rb -E production时，我在浏览器中收到消息:

When I run bundle exec unicorn -c config/unicorn.rb -E production I get the message in the browser:

The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved.

但是，如果我只是通过bundle exec rails server运行rails应用程序，则可以通过[IP]:3000

However if I just run the rails app via bundle exec rails server I can successfully access via [IP]:3000

我怀疑错误与ActionController::RoutingError (No route matches [GET] "/"):有关，但是我缺乏了解解决方案的知识.

I suspect the error is something to do with ActionController::RoutingError (No route matches [GET] "/"): however I lack the rails knowledge to figure out the fix.

推荐答案

您需要在routes.rb文件中设置根路由.

You need to setup a root route in routes.rb file.

root :to => 'index#index'

第一个索引是控制器名称(IndexController)，第二个索引是IndexController中的动作名称.

Where the first index is the controller name (IndexController) and the second index is the action name in the IndexController.
