前提
- macOS：13.0（22A380）
- ruby：3.1.4p223 (2023-03-30 revision 957bb7cb81) [arm64-darwin22]
- rails：7.0.4
- bundler：2.3.26
- mysql2：0.5.5
サマリー
- mysql2インストール時に、opensslの読み込み先が間違っているためエラーになる
- なので、読み込み先を指定してあげる必要がある
- 自分の場合は、opensslのリンク先の設定を行い、mysql2のビルドオプションの指定で解決した

An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.5' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:

こちらを参考にして、mysqlが入っていないことが原因と推測
brew install mysql

Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load

opensslの読み込みが上手くいっていないよう
% ls /usr/local/opt/openssl/lib/
ls: /usr/local/opt/openssl/lib/: No such file or directory
こちらを参考に、opensslのリンク先の設定を行う
$ openssl version
LibreSSL ***
$ brew install openssl@3
$ brew link --force openssl@3
$ echo 'export PATH="/opt/homebrew/opt/openssl@3/bin:$PATH"' >> ~/.zshrc
$ source ~/.zshrc
% openssl version
OpenSSL 3.2.0 23 Nov 2023 (Library: OpenSSL 3.2.0 23 Nov 2023)
次にこちらを参考に、mysql2のビルドオプションを設定する
% brew --prefix openssl
/opt/homebrew/opt/openssl@3
% brew --prefix zstd
/opt/homebrew/opt/zstd
% bundle config --local build.mysql2 "--with-ldflags=-L/opt/homebrew/opt/openssl@3/lib --with-opt-dir=/opt/homebrew/opt/zstd"
