嗨，我有一个rails 5 app ubuntu 16.04 puma这里是从puma.stderr.log输出
/home/ashish/.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/activerecord-5.1.4/lib/active_record/connection_adapters/connection_specification.rb:188:in `rescue in spec': Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). (Gem::LoadError)
