  • Donc, vous dites que "Ce n'est certainement pas l'installation de plusieurs paquets" - que fait-il dans votre cas? Quelle est la sortie de la console après l'exécution de cette commande?
  • Il donne une longue liste d'erreur, qu'il ne produit pas, lors de l'installation de paquets individuellement. Voir mise à jour le post.
  • Entendez-vous des erreurs? Ces paquets ont besoin de Python, installer Python avec la bonne version et ré-installer, vous ne verrez pas ces erreurs à nouveau.
