Django ModuleNotFoundError all of a sudden-CodePudding

All of a sudden, my django project is not working anymore. Not only my actual branch but even master. This happened after coming back to my project after the night. The error I have is when I run any command I have this message :

ModuleNotFoundError: No module named 'pur_beurre.pur_beurre'

(Note : pur_beurre is the name of my project)

When I run python manage.py, I have the list of all possible commands plus this new message in red :

Note that only Django core commands are listed as settings are not properly configured (error: No module named 'pur_beurre.pur_beurre').

I tried to put pur_beurre and pur_beurre.pur_beurre in my installed app in settings.py but its not working.

PS C:\Users\tdechanet.TWM\Documents\OpenClassrooms\p8\code\pur_beurre> python .\manage.py runserver

Here is my installed apps :

INSTALLED_APPS = [
    'main_site.apps.MainSiteConfig',
    'user_management.apps.UserManagementConfig',
    'django.contrib.admin',

CodePudding user response：

the first line in manage.py is

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'pur_beurre.settings')

which sets the standard path to settings BUT only as default if DJANGO_SETTINGS_MODULE has not been defined on system level.

Your error message looks like you have defined on windows a environement variabel DJANGO_SETTINGS_MODULE="pur_beurre.pur_beurre"

just to check add this line in manage.py at the beginning:

print(os.environ['DJANGO_SETTINGS_MODULE'])

Then check windows settings for the variabel, correct or delete and just in case reboot.
