##前提と目的
ローカル環境にてrails tutorial中herokuにデプロイ中に下記のエラーが発生。
Could not detect rake tasks ensure you can run `$ bundle exec rake -P` against your app and using the production group of your Gemfile.
下記にデプロイ中の様子で正常だと思ったとこ以外を記載。(長くてすいません。)

gemfile.rb は以下

とりあえずエラー文に言われた通り実行。
toy_app % bundle exec rake -P
その後git commit
してpush
してデプロイしたが、最初と全く同じエラー文が表示された。
AWS cloud9ではできたのだが、ローカルではできず、デプロイ中のlogの違いは今回取り上げた部分のみだと思うのだが、、、
わかる方いらっしゃいましたら、ご教授をお願いしたいです。
よろしくお願いいたします。
