は、ロガーレベルのデバッグですか？ 「このスレッド」（https://github.com/rails/sprockets-rails/issues/376）が役立つかどうかを確認してください。 – kiddorails
@kiddorailsに感謝しますが、それでも同じエラーがあります。このエラーは、リモートから別の 'schema.rb'を貼り付けた直後に発生しました。再度、感謝します。 –
それから 'rm db/schema.rb'を試してください。あなたのローカルデータベースのスキーマが正しいと確信できたら、 'rake db：schema：dump'または' rake db：drop db：create db：migrate' – kiddorails
