Installation échoue sous OSX 10.13.6

[josephmure]

Je viens d'essayer d'installer la librairie sur l'ordinateur de quelqu'un qui possède un MAC (OS X version 10.13.6). J'ai suivi la méthode indiquée dans le readme :

git clone https://github.com/brunoscherrer/retraites.git
cd retraites
python setup.py install

Au moment du clonage, la branche master est au commit 53fa76e.
La dernière commande échoue, pourtant Python 2.7 est bien installé

$ python --version
Python 2.7.13

Le message d'erreur est le suivant

$ python setup.py install

Le site existe pourtant :

Le module pytest-runner n'existe peut-être pas pour Mac. Est-il strictement nécessaire pour le module retraites ?

[josephmure]

En effet, les scripts test_etudeimpact.py et test_retraites.py utilisent unittest et non pytest.

[mbaudin47]

unittest est dans Python et ne nécessite donc pas de module supplémentaire :

https://docs.python.org/3/library/unittest.html

Je me charge de corriger cela.
