Por favor marque la solución here .
Sin ocurrencia de la cadena visitor dentro de mi proyecto, así que estoy confundido.
Aquí es el volcado completo:
$ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:migrate
rake aborted!
