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.
In Gemfile:


gem install mysql2 -v '0.5.3' --source 'https://rubygems.org/'を実行するように指示があるので、実行してください。

もう一度bundle installを実行します。


Building native extensions. This could take a while...
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.
Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load
Setting libpath to /usr/local/Cellar/mysql/8.0.22/lib

brew info opensslを実行してください。

A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
and run
openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.
If you need to have openssl@1.1 first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc
For compilers to find openssl@1.1 you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
For pkg-config to find openssl@1.1 you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"


bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl@1.1/lib --with-cppflags=-I/usr/local/opt/openssl@1.1/include"

bundle installを再度実行すると、インストールができるはずです。
