私はこのリンクをたどって、Github に個人ウェブサイトをセットアップしています。 Web サイトは正常に展開され、アクセスできるようになりました。
私の Ruby のバージョンは 3.3.0 で、Gem のバージョンは 3.5.4 です。このリンクに記載されている Webrick も追加しました。
ただし、bundle install および Bundle exec jekyllserve を実行した後、ローカルでビルドできません。エラーは

私の _config.yml は
# Welcome to Jekyll!
#
# This config file is meant for settings that affect your whole blog, values
# which you are expected to set up once and rarely edit after that. If you find
# yourself editing this file very often, consider using Jekyll's data files
# feature for the data you need to update frequently.
#
# For technical reasons, this file is *NOT* reloaded automatically when you use
# 'bundle exec jekyll serve'. If you change this file, please restart the server process.
#
# If you need help with YAML syntax, here are some quick references for you:

#
# Site settings
# These are used to personalize your new site. If you look in the HTML files,
# you will see them accessed via {{ site.title }}, {{ site.email }}, and so on.
# You can create any custom variable you would like, and they will be accessible
# in the templates via {{ site.myvariable }}.
title: username
email: [email protected]
description: >- # this means to ignore newlines until "baseurl:"
Write an awesome description for your new site here. You can edit this
line in _config.yml. It will appear in your document head meta (for
Google search results) and in your feed.xml site description.
baseurl: / # the subpath of your site, e.g. /blog
url: https://username.github.io # the base hostname & protocol for your site, e.g. http://example.com
twitter_username: username
github_username: username
# Build settings
theme: minima
plugins:
- jekyll-feed

これは技術的には機能しますが、それが最善の方法であるか、推奨される方法であるかはわかりません。
私は上記の投稿と同じ問題に苦労していましたが、最近、調査結果をまとめた投稿 (実際には初めての投稿) を Medium に公開しました。
TL;DR - 簡単に言うと、Ruby のバージョンを管理する簡単な方法として、brew などを介してインストールするのではなく、rbenv をインストールして使用して Ruby のバージョンを管理することをお勧めします。
その方法は次のとおりです。コマンドから $ を削除することを忘れないでください。
$ brew install rbenv ruby-build
$ echo 'eval "$(rbenv init - zsh)"' >> ~/.zshrc
$ source ~/.zshrc
次に、必要な Ruby バージョンをインストールします。
$ rbenv install 3.2.3
最後に、インストールされた Ruby をグローバル スコープかローカル スコープ、あるいはその両方に設定します。
$ rbenv global 3.2.3
$ rbenv local 3.2.3
$ ruby -v
ruby 3.2.3
最後にバンドラー gem をインストールします。
$ gem install bundler
$ bundle -v
Bundler version 2.5.5
さあ、準備完了です！
