Cloud９でRailsの投稿機能作成でエラーが出る

Question

＜前提・実現したいこと＞
・エラーコードのどこの部分に解決の糸口になる問題点が書かれているか知りたい
・エラーの意味も詳しく知りたい

＜質問の内容＞
Cloud9を使ってサンプルでRailsでの投稿機能を作ろうとしています。
専用のテキストのコードを１から全てコピペして、実装しましたがエラーが出てしまったため、何度も１からやり直しましたが、同じようなエラーメッセージになるため、解決の糸口がいただきたいと思うます。全文コピペなので、スペルミスはないと思いますので、そもそもの設定やコードの書く場所などがおかしなことになっているのかどうか教えていただきたいです。

＜発生している問題・エラーメッセージ＞
=> Booting Puma
=> Rails 5.2.6 application starting in development
=> Run rails server -h for more startup options
Exiting

Answer 1

エラー最後の部分(以下の部分に書いてあると思われます)
configディレクトリ配下のroutes.rbの5行目でエラーを吐いています
SyntaxErrorは構文のエラーなのでクオンテーションがうまく囲えていなかったり、鉤括弧がうまくかこえていなかったりするとこのエラーを出力します

load: /home/ec2-user/environment/sample_app/config/routes.rb:5: syntax error, unexpected tIDENTIFIER, expecting end (SyntaxError)
