Любой помощи будет оценен, как я выполнил все другие темы, не радости. Заранее спасибо

Answer 1

вы должны внимательно прочитать сообщение об ошибке, это там;)

Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (mysql2 is not part of the bundle. Add it to Gemfile.) (LoadError) 

просто добавить gem 'mysql2' к вашему Gemfile, и запустить bundle install.
