バージョン
Rails 5.2.4.2
Ruby 2.6.6p146 (2020-03-31 revision 67876) [x64-mingw32]

rails s と入れるとこんなものが出てきてしまいます。
以下のコードは何を言っているのでしょうか？初心者で戸惑っています...
どなたか分かる方いらっしゃいませんか？

bundle installしましたか？

ありがとうございます。以前以下の記事と同じ状況で、とりあえずこれ通りにやってみました。 bundle -v とコマンドプロンプトでやってもちゃんとBundler version 1. 17.2と出てきます。これはインストールされていると言うことでしょうか？ https://qiita.com/riest817/items/d23e8fcd987ae008eb6d

はい！大丈夫です。私が実装中のアプリで試してみたところ、Bundler version 1.17.3と表示されました。17.2と17.3の違いは特に気にしなくて良いと思います。

そうですか！よかったです。しかしbundleもちゃんと入っているとなると他にエラーが出る原因として何が考えられるでしょうか...

コマンドで $ gem uninstall -a sqlite3 $ gem install sqlite3 --platform=rubyとしてみてください
