Can't use pytest-bdd after installation
<p>I installed pytest-bdd at <code>/home/marlu/.local</code> using <code>python setup.py install --user</code>, since I don't have admin privileges. Both python2.7 and pytest are located at /usr/bin/. When I check if pytest-bdd is working correctly by running <code>py.test --version</code> I get an error, could anyone tell me why? Thanks!</p>

<p>Error output:</p>
