ruby-on-rails - Heroku Rails ページが見つかりません

Question

サンプルの Rails アプリを heroku にデプロイしようとしています。非常に基本的なアプリを作成し、git リポジトリを追加し、すべてをコミットして「heroku create」を実行した後、heroku にプッシュしました。端末にエラーはまったくありませんが、正しいアドレスでブラウザーを開くと、次のようになります。

The page you were looking for doesn't exist.

You may have mistyped the address or the page may have moved.

3 時間検索し、アプリのデプロイ方法に関する heroku チュートリアルを使用しましたが、何が間違っているのかわかりません。これが私のGemfileです：

source 'https://rubygems.org'

ruby '2.0.0'

gem 'rails', '4.0.0.beta1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'json'

group :production do
  gem 'pg'
  gem 'rails', '4.0.0.beta1'
  gem 'railties', '4.0.0.beta1'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  #gem 'sass-rails',   '~> 3.2.3'
  gem 'sass-rails',   '~> 4.0.0.beta1'
  #gem 'coffee-rails', '~> 3.2.1'
  gem 'coffee-rails', '~> 4.0.0.beta1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

上記の手順を数回繰り返しましたが、うまくいきませんでした。ありがとう！

まず、Rails でのルーティングに関する適切なガイドがここにあります。

アプリにモデルがあり、記事コントローラーがあるとしますArticle。このリソースのルートを config/routes.rb で定義する必要があります。index, show new, create, edit, updateRails では、とのルートをdestroy1 行で追加できます。

resources :articles

これは次のようにマッピングされます。

GET     /articles           index   display a list of all articles
GET     /articles/new       new     return an HTML form for creating a new article

Railsの「エッジ」バージョン（4+）を（おそらく意図せずに）使用しようとしていることに気付きました。

私は今のところ 3.x バージョンに固執しますが、それはおそらくチュートリアルが想定していることです。

これを使用して、特定のバージョン (この場合は 3.2) のアプリを作成できます。

rails _3.2_ new myapp

システムにそのバージョンのレールがない場合は、インストールする必要があるかもしれません。

gem install -v=3.2 rails

または、それが失敗した場合、

sudo gem install rails -v3.2

上記の理由により、現在の Heroku の指示に従うと、Rails 3 が想定され、そのバージョンではデフォルトのルートパスと public/index.html ファイルが実行されます。
