перенос базы данных простых рельсов в mysql

Я заинтересован в создании приложения rails с базой данных mysql. Я новичок в рельсах и просто пытаюсь начать что-то простое:

rails -d mysql MyMoviesSQL
cd MyMoviesSQL
script/generate scaffold Movies title:string rating:integer
rake db:migrate

Я вижу следующую ошибку:

rake aborted!
NoMethodError: undefined method `ord' for 0:Fixnum: SET NAMES 'utf8'

если я делаю трассировку:

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
rake aborted!
NoMethodError: undefined method `ord' for 0:Fixnum: SET NAMES 'utf8'

спасибо за помощь
