herokuにデプロイしても application errorと表示される

Question

railsチュートリアルの第三章を勉強しております。
windows cloud9を使ってます。

herokuにデプロイしてもapplication errorと表示されます。
migrateは行っております。
heroku logsではat=error, code=H10, desc="App crashed", status=503の部分が赤字で表示されます。
heroku restart を行うと
Restarting web.1 dyno on ⬢ application_afternoon-mesa-73900... !
▸ Couldn't find that app.
と表示されます。
rails console で見てみると

と表示去れます。
はじめの方のErrno::EACCESの部分に原因があるのではないかと思うのですが、解決方法がわかりません。
どなたかお分かりになる方お教え頂ければと思います。

まだ解決してないです？

Answer 1

ありがとうございました。
どうしても原因がわからなかったので、一回ファイルを元から削除して、railsチュートリアルの３章の始めからやり直しました。
順番が悪かったのか、今回は正しい順序で行うと問題なくherokuに反映されました。
お答え頂き、お手数お掛け致しました。ありがとうございました。

Answer 2

追記になります。
すみません、rails db:migrateを行っていたんですが、dbにmigrateのファイルがありませんでした。
何か不足してて、コードが反映されていないと思うんですが、migrateする前には、$ rails generate scaffold User name:string email:string　というこのコードを入力してscaffoldを入れておかないとmigrate出来ないんでしょうか？

Answer 3

追記になります。
git push heroku を行うと途中に黄色の文字で　warningを記述されます。
これは今までなかったと思うので、ここにも原因の理由があるのかもしれません。そのコードを載せておきます。
