Q&A
前提・実現したいこと
現在rails チュートリアル第５章を進めているRubyonrails初心者です。
５章の最後にgit push herokuを行うのですが、その際下記のエラーが出てしまいました。
チュートリアルを進める際に、途中で個人的にコードを加えたりしていない・今までgit push herokuは問題なく行えていたため、なぜこのようなことが起こるかさっぱりわかりません。
エラー文をネットで検索しましたが、似たような質問がなかったため、お答えいただけると大変ありがたく存じます。
発生している問題・エラーメッセージ
エラーメッセージは下記のとおりです。

エラーと思われる部分が非常に多いのですが、以下の部分が原因なのかなと思っています。

SyntaxError: /tmp/build_25de9153d8b72e9d14a08fa28c9882ed/config/application.rb:18: syntax error, unexpected <<, expecting end-of-input
試したこと
bundle installをし直したり、Gemfile.lockを削除するといいとのネットの投稿のとおり削除したりしましたが、まったく変化はありません。
エラー文の中に$ bundle exec rake -Pをするようにとの指示も出ているので、してみましたが、解決しませんでした。
補足情報（FW/ツールのバージョンなど）
参考までにGemfileを載せたいと思います。

そうですね、その推測はするどいです。特に最後の行ですね。
というわけで、config/application.rbの18行目にsyntax errorがあるようなのですが、そのファイルの18行目と、その前後に<<<<<<<<< saved versionみたいな変な行が入っていないでしょうか。それを修正すると一歩前進しそうです。
