デプロイメント後にHerokuアプリがクラッシュする

Question

私はこの数日間、RubyとRoRを学んできました。私はちょうど私の開発マシン上にダミーのアプリケーションを完了し、それは完全に動作しています。それをHerokuにプッシュした後、アプリがクラッシュします。

数日前に始まったので、私はほとんどRubyとRoRを知っていません。なぜエラーが起きているのか把握するのは少し怖いです。何か案は？私はHerokuにプッシュして道のすべてのステップでテストすべきだったが、あなたは生きていると思う。

Answer 1

ログファイルを詳しく見てください。この行があります：

Please install the 
gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to  Gemfile.) 

基本的に、あなたはそれをサポートしていないsqlite3のサーバー、とHerokuのインスタンスを実行しようとしている（最も可能性が高いです）。あなたのgemfileでは、次を配置する必要があります。

group :development, :test do 
    gem 'sqlite3' 
end 

group :production do 
    gem 'pg' 
end 

rebundle、コミットとHerokuのにrepush、あなたは問題ないはずです。
