I just hit this problem where Capybara fails while running under Rails 3 with this error when trying to follow a link.

undefined local variable or method `node' for #<Capybara::Driver::RackTest::Node:object_id> (NameError)

According to the Jonas Nicklas the author, it’s solved by removing the line in features/support/env.rb which enables Javascript emulation, because that feature no longer exists in Capybara.

Comment out or delete this:

require 'cucumber/rails/capybara_javascript_emulation' # Lets you click links with onclick javascript handlers without using @culerity or @javascript

And all should be well.
