当我尝试运行bin / rails服务器时，我的服务器无法启动它只会显示一些连接错误或者其他什么。我尝试捆绑了exec rails服务器，但它也没有用。

您必须从顶部阅读堆栈跟踪才能了解正在进行的操作：

Warning: You're using Rubygems 2.0.14 with Spring. Upgrade to at least Rubygems 2.1.0 and run `gem pristine --all` for better startup performance.

这只是一个警告，您可能希望稍后解决此问题。但是你现在可以忽略它，因为它只是一个警告。

=> Booting WEBrick
=> Rails 4.2.1 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

这是Rails启动时的默认输出。

但现在有趣的部分：

Exiting
/Users/i/blog/config/routes.rb:7:in `<top (required)>': undefined method `resources' for main:Object (NoMethodError)

此行告诉您undefined method 'resources'的{​​{1}}行（或该行之前）有7。

问题是由不在外config/routes.rb块内的第二个resources :articles块引起的。此外，您有两个Rails.application.routes.draw，但您只需要一个resources :articles。将以下版本复制到config/routes.rb以解决您的问题：

Rails.application.routes.draw do

  root 'welcome#index'

  resources :articles do
    resources :comments
  end

end
