ライブラリのバージョンに互換性がないため、Rails アプリを作成できません - ロード エラー
概要
初めての投稿はこちらから！ Rails アプリを構築しようとしていますが、開始するのが非常に困難です。 Rails と Ruby をインストールしましたが、アプリ (Miless-MBP:railstest Mile$ Rails new tester2) を作成するたびに、多数のエラーが発生します。完全なログは以下にありますが、ここでは 4 つをリストします。
みなさん、本当にありがとうございました！

解決策
私も同じ問題を抱えていました。以下を使用して msgpack gem を完全に削除する必要があります。
gem uninstall msgpack
次に、それを再インストールして、現在使用している Ruby のバージョンに対してライブラリがビルドされるようにします。
次のことも試してみてください:
bundle install --redownload
これにより、gem が再インストールされ、現在使用している Ruby のバージョンでリンクされたライブラリが再構築されます。
