本番環境のブラウザコンソールで以下のエラーが出ております。

【rails6】本番環境でJSが読み込まれない

gemfileにgem 'pry-rails'を追加したらrails c や rails s が起動しなくなった。

逆にgenfileのgem 'pry-rails'をコメントアウトにしたら起動しました。
gem 'pry-rails'を有効にして起動する方法はございませんでしょうか？
よろしくお願いします！

pry-rails を追加したが

### 環境
cloud9
ruby 2.6.3
rails 5.1.6

railsチュートリアルにて、
```ここに言語を入力
rails s
```
でサーバーを立ち上げた後、
リスト1.7に従いコントローラにhelloを追加
```ここに言語を入力
class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  def hello
    render html: "hello, world!"
  end
end
```
さらにリスト1.9に従いルーティングを設定
```ここに言語を入力
Rails.application.routes.draw do
  root 'application#hello'
end
```

そしてブラウザへアクセスすると...
![イメージ説明](1b8b0704406b45f0381df832af3d8b85.jpeg)
このように表示されます。
考えられる原因・対処法を教えていただきたいです。
宜しくお願い致します。
