problems to run

[dunossauro]

Hello, I've had some problems running pycukes.

$ pycukes stories/teste.story 
Traceback (most recent call last):
  File "/usr/bin/pycukes", line 11, in <module>
    load_entry_point('pycukes==0.2', 'console_scripts', 'pycukes')()
  File "/usr/lib/python3.5/site-packages/pkg_resources/__init__.py", line 564, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python3.5/site-packages/pkg_resources/__init__.py", line 2621, in load_entry_point
    return ep.load()
  File "/usr/lib/python3.5/site-packages/pkg_resources/__init__.py", line 2281, in load
    return self.resolve()
  File "/usr/lib/python3.5/site-packages/pkg_resources/__init__.py", line 2287, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "/usr/lib/python3.5/site-packages/pycukes/__init__.py", line 1, in <module>
    from runner import StoryRunner
ImportError: No module named 'runner'

Could you give me some advice concerning how to execute the test without errors?

I've tried installing runner (pip install runner), but it also didn't work.
