Je travaille sur une application Flask depuis quelques semaines. Je l'ai terminé aujourd'hui et je suis allé le déployer ... et maintenant il ne se lancera pas.
Je n'ai ajouté ou supprimé aucun code, alors supposez que quelque chose a changé dans le processus de déploiement?
Quoi qu'il en soit, voici l'erreur complète affichée dans le terminal:

J'ai essayé de réinstaller flask& flask_restplusmais pas de chance.
