undefined method `configuration' for Rails:Module (NoMethodError)

使用cucumber包如下错误：

undefined method `configuration' for Rails:Module (NoMethodError)
C:/software/InstantRails-2/ruby/lib/ruby/gems/1.8/gems/cucumber-0.3.11/bin/../lib/cucumber/rails/world.rb:41:in `use_transactional_fixtures'
./features/support/env.rb:11

解决办法:

根据提示，把env.rb这一行注释掉就好了。
#Cucumber::Rails.use_transactional_fixtures
