Ошибка в rack mysql2 "unknown database"

Я следую инструкциям из переносного пакета из предыдущей группы. Я не слишком разбираюсь в рельсах или mysql2. Я нахожусь в Windows.

Когда я это сделаю:

rake db:migrate RAILS_ENV=production

Это вывод:

C:\jcccf-goslowserver-e30bf00>rake db:migrate RAILS_ENV=production
(in C:/jcccf-goslowserver-e30bf00)
rake aborted!

Я читал о том, что нужно использовать db: сначала создать, но я беспокоюсь, что я буду стирать то, что уже есть в исходном коде передачи. Разве это не имеет смысла?

Это инструкции, которые мне дали.

...
3. Configure your MySQL settings in config/database.yml for "production"
4. Open the console (cmd on Windows, Terminal on Mac/Linux) and cd to the GoSlow directory
5. Type "rake db:migrate RAILS_ENV=production" and press enter.
6. Type "rake bootstrap:all RAILS_ENV=production" and press enter.

(тогда я предполагаю, что я просто делаю сервер rails, он не указывается)

Вот мой файл database.yml, который находится в config/database.yml относительно того, где я набираю эти команды.

# MySQL.  Versions 4.1 and 5.0 are recommended.
#
# Install the MySQL driver:
#   gem install mysql2
#
# And be sure to use new-style password hashing:
#   http://dev.mysql.com/doc/refman/5.0/en/old-client.html
development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: GoSlow_development
  pool: 5
  username: root
  password:
  host: localhost

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: GoSlow_test
  pool: 5
  username: root
  password:
  host: localhost

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: GoSlow_production
  pool: 5
  username: root
  password: [MyPassword]
  host: localhost

Любые мысли о том, почему он не будет работать?
