私はレールに不慣れで、問題を特定できません。私はDeviseに関するRailsCastチュートリアル＃209に従っていて、実行するとエラーが発生します：rails g devise：views

エラーは次のとおりです。

rubyのバージョンを変更して問題が解決するかどうかを確認しましたが、正確な問題を見つけることができませんでした。他の誰かがこのエラーに遭遇しましたか？

実行が終了するとすぐにコンソールに印刷されるように、実行する必要のある手動セットアップが欠落しているようです（@douguiと@ janders223が指摘しているように、それはおそらくあなたのルートです）rails generate devise:install。

===============================================================================

Some setup you must do manually if you haven't yet:

  1. Ensure you have defined default url options in your environments files. Here 
     is an example of default_url_options appropriate for a development environment 
     in config/environments/development.rb:

       config.action_mailer.default_url_options = { :host => 'localhost:3000' }

     In production, :host should be set to the actual host of your application.

  2. Ensure you have defined root_url to *something* in your config/routes.rb.
     For example:

       root :to => "home#index"

  3. Ensure you have flash messages in app/views/layouts/application.html.erb.
     For example:

       <p class="notice"><%= notice %></p>
       <p class="alert"><%= alert %></p>

  4. If you are deploying Rails 3.1 on Heroku, you may want to set:

       config.assets.initialize_on_precompile = false

     On config/application.rb forcing your application to not access the DB
     or load models when precompiling your assets.
