Bonjour,

Je suis en train de suivre le tuto de Serge Tahé et j'en suis arrivé au chapitre de l'utilisation de PostGres.
Mais j'ai une erreur sur l'installation de psycopg2 et je ne parviens pas à m'en sortir.

Dans PyCharm, la ligne de de commande "pip install psycopg2" provoque l'affichage de message d'erreur
