Sometimes getting an "Invalid Route Name" Error in Rails

I am getting the following error only on occasion when I attempt to load up my Rails app in localhost.

Invalid route name, already in use: 'root' You may have defined two routes with the same name using the :as option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with resources as explained here: http://guides.rubyonrails.org/routing.html#restricting-the-routes-created

For some reason, it only happens every now and again, and generally goes away after I refresh the page once. The file it is calling into question has this as the code (line causing the error indicated):

Rails.application.routes.draw do
  get 'welcome/index'
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".

# You can have the root of your site routed with "root"

  Rails.application.routes do
    resources :articles
    root 'welcome#index' #-->This is the line that causes the error
  end

  resources :articles do
    resources :comments
  end
end

I am really new to Rails, and I'm not sure what is causing the problem or if would even be a problem if I were to actually host this beginner project on the web. Also, if it helps, I am running Ruby 2.2.2 and Rails 4.2.1.

Thank you in advance for the help!

You have two routes pointing to the same page index, get rid of your get route

get 'welcome/index'

Also your root route is nested that should be moved outside since the root route is the root of your entire app and not a specific resource

You have (Rails.application.routes) nested inside (Rails.application.routes.draw). Run rake routes and you will see that you have resources for articles twice. Furthermore, you have root 'welcome#index' nested inside and that is why you are getting the error. Your routes should look like this 

Rails.application.routes.draw do
  get 'welcome/index' => 'welcome#index'
  root 'welcome#index' 
  resources :articles do
    resources :comments
  end
end

Note that the route of your application meaning(/) and (/welcome/index) both point to the welcome controller index action. You don't really need get 'welcome/index' => 'welcome#index' and you can delete that line and use root when ever you need the index action from the welcome controller.

Try using the "Full" syntax.

root :to=> "some#action"
