An error occurred while installing mysql2 (0.5.3), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.3' --source 'https://rubygems.org/'` succeeds before bundling.

mysql2

解決策

方法1

bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include"
bundle install

方法2

brew install openssl
bundle config --local build.mysql2 --with-opt-dir="$(brew --prefix openssl)"
bundle install

どちらの方法も、プロジェクトごとに設定が面倒なら--localではなく--globalで設定すればおk。

🤔

opensslにリンクされてなかったんだなぁ
