Heroku App Crashed

Question

私のアプリがクラッシュした理由を理解しようとしていますが、スラッグのサイズは54MBと非常に大きくなりますが、コンピュータのフォルダサイズは3MBのようです。ログファイルは次のとおりです。しかし、Herokuの問題を把握することはできません）

Answer 1

あなたのログファイル

2011-11-12T20でより深く見て取る：43：37 + 00：00アプリを[web.1] ： /app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.1/lib/active_record/connection_adapters/abstract/connection_specification.rb:71:in rescue in establish_connection': Please install the postgresql adapter: gem insta ll activerecord-postgresql-adapter`（pgはバンドルの一部ではありません。 ） Gemfileに追加してください。）（RuntimeError）

問題の原因です。

Herokuのは、PostgreSQLを提供 - その結果、あなたはあなたのGemfileにPGの宝石を追加する必要があります - あなたは、コミットとHerokuのにrepush発展のために、現在

group :development do 
    gem 'sqlite3' 
end 

group :production do 
    gem 'pg' 
end 

rebundleをsqlite3のを使用していて、あなたは問題ないはず想定します。
