MySql Connect потерял в кристальном языке с Kemal

/ 05 октября 2018

Пробую соединение Kemal Framework с crystal-mysql.Это мой осколок: 

mysql:
github: crystal-lang/crystal-mysql
db:
    github: crystal-lang/crystal-db

И это мое соединение: 

db = DB.open "mysql://root:password@localhost:787878/book"

Но, если я бегу crystal src/book.cr, у меня есть эта ошибка: 

Unhandled exception:  (DB::ConnectionLost)
  from lib/mysql/src/mysql/read_packet.cr:16:7 in 'initialize'
  from lib/mysql/src/mysql/read_packet.cr:6:3 in 'new'

  from ???

Как я могу это исправить.
