An error occurred while installing ffi (1.15.0), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.15.0' --source 'https://rubygems.org/'` succeeds before bundling.

個別インストール gem install ffi -v '1.15.0' --source 'https://rubygems.org/' ではインストールできても bundle install ではインストールできない

解決法

% xcode-select --install
% bundle install --path vendor/bundle
