■背景  
<https://prog-8.com/docs/ruby-env>  
上記プロゲートのサイトに沿って、railsインストールを試みています。

■やりたいこと  
rails7.03をインストールし、ローカルにて開発環境を構築したい

■環境  
M1チップ macbookpro2020  
Ventura ver13.0  
※環境詳細は下記参考を参照願います

■現状  
`rails -v` 実行でエラーが出る  
(`rails new sample_app`でも同じエラー)

※エラー文にて読み込めないと言われているetcは`gem list`では表示されている

GEMはあるのにRailsがインストールできない状態？

■既に試したこと（しかし同じエラー発生）  
Homebrew, rbenv, rubyアンインストールの上、再度インストールし、ローカル環境構築試みました。

PC再起動、OSアプデ

■実際に出てるエラーメッセージ
