je viens de finir un tutoriels sur kivy et quand j'exporte pour android avec la commande: "buildozer android debug deploy run" le terminal me retourne une erreur liée à cython et il faut noter que j'ai installé cython contrairement à ce que la sortie me fait comprendre.

je comprends pas ce qui se passe, de l'aide s'il vous plaît et merci d'avance. voici la sortie du terminal avec un log_level = 2:
