[RUBY] bundle install does not install mysql2


I get an error every time in my local environment so make a note of the solution

$ bundle install --path vendor/bundle 
Error statement ↓
An error occurred while installing mysql2 (0.5.3), and Bundler cannot continue.


$ bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl/lib"
$ bundle install --path vendor/bundle

When the above command is executed, the following line will be added to .bundle / config

BUNDLE_BUILD__MYSQL2: "--with-ldflags=-L/usr/local/opt/openssl/lib"

Will come to be.
