Rails 4无法启动服务器或db：migrate

Question

New to rails 4 here, i've had a look through other questions but can't seem to find the answer, feel free to point me in the right direction!

Here is my error code for attempting to run the rails server:

Tasks: TOP => db:migrate => environment

I apologise if the question is already answered or obvious - i honestly couldn't find it.

Thanks in advance!

config/routes.rb file:

  Autostudy::Application.routes.draw do
  resources :posts

  get "admin" => "admin#index" 
  resources :resources

  resources :contents

  resources :courses

  resources :user_profiles


  authenticated :user do
    root "home#index"
  end
  root "home#index"
  resources :users, :only => [:index, :show, :edit, :update ]
  get '/auth/:provider/callback' => 'sessions#create'
  get '/signin' => 'sessions#new', :as => :signin
  get '/signout' => 'sessions#destroy', :as => :signout
  get '/auth/failure' => 'sessions#failure'
end

Answer 1

thanks for the tips. Turns out it was this part in my routes file it didn't like:

  authenticated :user do
    root "home#index"
  end
  root "home#index"

So i changed it back to just:

    root "home#index"

And everything works fine. Thanks, i'll just do authenticated login pages a different way.
