Bonjour,
Je débute en python il y a quelques jours.
Je souhaite installer la bibliothèque openpyxl afin de pouvoir faire des traitement sur des fichiers Excel.
J'ai exécuté la commande: pip install openpyxl mais ça ne marche pas, et voici ce que j'obtiens:

Pourriez-vous m'éclaircir d'où vient ce problème svp?
