Erreur lors de l'exécution de Flask Tutoriel: Flaskr App

Question

J'ai un peu de mal à l'exécuter dans mon invite de commande (je suis déjà dans mon répertoire flaskr).

set FLASK_APP=flaskr set DEBUG_MODE=1 flask run

http://flask.pocoo.org/docs/0.11/tutorial/setup/#tutorial-setup

J'ai suivi toutes les étapes jusqu'à présent. J'ai lu des choses sur virtualenv et d'autres choses, mais ça n'a pas vraiment de sens - est-ce que je devrais jouer avec ça ou est-ce qu'il y a une solution plus facile?

Ma sortie/log d'erreur:

Answer 1

Vous devez installer votre application comme un package sur votre virtualenv ou déclarer l'extension de fichier comme FLASK_APP=flaskr.py
