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
