回答1:
pytest-cov package is required if you want to pass --cov arguments to pytest, by default it should not be passed though. Are you using a modified version of py.test?
pip install pytest-cov would fix your issue.

For those who use CentOS 6, the version of setuptools is old and you need to upgrade it also:
pip install pytest-cov pip install --upgrade setuptools Just after installing pip install pytest-cov:
~ # py.test --version This is pytest version 3.0.5, imported from /usr/lib/python2.6/site-packages/pytest.pyc ~ # pip install --upgrade setuptools [...] Successfully installed setuptools-30.3.0 ~ # py.test --version This is pytest version 3.0.5, imported from /usr/lib/python2.6/site-packages/pytest.pyc setuptools registered plugins: pytest-cov-2.4.0 at /usr/lib/python2.6/site-packages/pytest_cov/plugin.py 回答3:
sdonk's answer helped me. But since I use pipenv, I had to run
pipenv install pytest_cov
