Rails tutorial のrails test でエラー発生

Question

前提・実現したいこと

M1チップ搭載のmacbookにてRails tutorialを学習しております。

第3章　3.3.1「最初のテスト」にて
デフォルトでtest/controllers/static_pages_controller_test.rbファイルに置いてあるテストを
rails testコマンドで実行し、検証するという内容ですが、
コマンドを実行したところ以下のようなエラーが発生いたしました。

試したこと

調べたところ、springを停止すればエラーが止まったとの記事を発見。

% sudo gem install spring

↓

% spring stop

でspringを停止。

しかし変わらず。
といった現状です。
どこが誤っているかアドバイスを頂けると幸いです。

補足情報（FW/ツールのバージョンなど）

M1 macbook使用

% bundle lock --add-plataform x86_64-linux
```を実行しherokuに対応

Answer 1

`require': cannot load such file -- rexml/document (LoadError)

REXML は ruby3.0 から標準添付されなくなりました。
Gemfile に gem "rexml" を追加して $ bundle、その後テストを実行してみてください。
