だから...私はdjangoアプリに取り組んでいる初心者ですがheroku run python manage.py syncdb
、virtualbox herokuを実行しようとすると、以下のように表示され続けます:

助けてくれてありがとう。
編集::問題は解決しました
base.pyを次のように保持します。
DATABASES = {'default' : dj_database_url.config() }
次に、デプロイする前にlocal.pyデータベースをコメントアウトします...
致命的なエラーが発生した場合: https ://devcenter.heroku.com/articles/postgres-logs-errors#fatal-role-rolename
その後、postgres.heroku.comにアクセスしてデータベースの色を見つけ、アプリにプロモートします。
すべてが今機能しているはずです:)
