Хмм ... поэтому я попытался удалить гем mysql2 и переустановить версию 0.2.7 гем
sudo gem uninstall mysql2 -i /Library/Ruby/Gems/1.8
И я изменил gemfile:
gem 'mysql2','0.2.7'
Ран Бандлер в каталоге моего приложения:
bundle install
Но он снова установил версию 0.3.2 !!!Может кто-нибудь помочь, я, честно говоря, не знаю, что здесь произошло.
