Can you please let me know what is your cucumber-rails version?

Just created a brand new rails 4.0 app with ruby-2.0.0-p247, and cucumber-rails 1.4.0 and it seems to be working as expected for a simple feature:

$ bundle exec cucumber --format pretty
Using the default profile...
Feature: Post feature

Scenario: Visit home page # features/posts.feature:3
When I go to the posts index # features/step_definitions/post_steps.rb:1
Then I should see 'Listing Posts' # features/step_definitions/post_steps.rb:5

1 scenario (1 passed)
2 steps (2 passed)

@Kosmas 1.4.0 too

[Kosmas]

OK, I think it's similar to '#252 and #253, which I thought was fixed. Need to have a look.

@ExReanimator try to use the master branch until the next version comes out. The problem should be resolved there.

@Kosmas Thank you! Resolved.
