J'ai également essayé d'utiliser pip3 , mais pas de chance. J'utilise Windows.

Answers

utilisez python 3.6 ou vous pouvez le construire à partir de la source

et à en juger par votre erreur, vous utilisez probablement une version différente et pip essaie de le construire à partir de la source. L'erreur est due au fait que les outils de création de Visual Studio ne sont pas installés. installez-le et cela résoudra votre erreur récupère-le d'ici
