Django version 4.0.2, using settings 'OurTools.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.

Maintenant si je supprime le fichier sqlite3, pour recréer une BD avec les opérations standards de Runserver, makemigrations, migrate, createsuperuser, etc
Là j'ai une erreur et je suis incapable de créer une BD, je suis inquiet de ne pas pouvoir déployer mon site en PROD si cela ne marche pas, voila le message que j'ai :
