Грешка при инсталиране на Spree ActiveRecord::ConnectionNotEstablished

Исках да създам онлайн магазин, използвайки релси и spree gem (http://spreecommerce.com/).

Оставяйки разработката на rails за известно време на моя mac (os x lion), инсталирах всичко от нулата, използвайки това ръководство: http://tecparatodos.com/2011/07/24/installing-ruby-on-rails-on-mac-os-x-lion/ и mysql с brew.

Следвах и „Документа за започване на работа“ на Spree http://guides.spreecommerce.com/getting_started.html

Възникналият проблем е, че използването на mysql, след конфигуриране на базата данни и напр. правейки а

rake db:create

Винаги получавам грешката ActiveRecord::ConnectionNotEstablished. Първо си помислих, че е свързано с моята инсталация на mysql, но след часове на проверка и преинсталация разбрах, че всъщност е заради скъпоценния камък на spree. Всеки път, когато добавя "gem 'spree'" към моя Gemfile, възниква тази грешка. Когато го премахна и направя "пакетно инсталиране", всичко работи добре. Имам известен опит с релси в проекти за изглед, но Spree е нещо ново за мен. Някаква идея какъв може да е проблемът?

Моята база данни.yml:

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: asiashop_development
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

# 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: asiashop_test
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: asiashop_production
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

И stracktrace, когато правя "rails c":

Както писах, това не може да е общ проблем с mysql връзката, защото всичко работи добре, стига да не използвам spree gem.
