Why am I getting "No module named 'django_celery_beat'" after installing django_celery_beat to my virtual env and putting it in INSTALLED_APPS?

Question

I am working on a Django project, and need to run cron tasks periodically to go through and delete all outdated files. I tried this same method with django_extensions and crontab, but I keep getting this same error. Within settings.py, I have:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'Data_Science_Web_App',
    'django_celery_beat',
]

in my INSTALLED_APPS section. 'Data_Science_Web_App' is the name of my application. When I used pip3 install django_celery_beat, it worked fine. However, when I try to migrate changes, I get this message:

(djangoenv) Daeyongs-Air:Data_Science_Project daeyong$ python3 manage.py migrate
Traceback (most recent call last):

  File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked
  ModuleNotFoundError: No module named 'django_celery_beat'

When I check using pip freeze, it is evident that django_celery_beat is there:

(djangoenv) Daeyongs-Air:Data_Science_Project daeyong$ pip freeze
amqp==5.0.2
asgiref==3.2.10
billiard==3.6.3.0
celery==5.0.5
certifi==2020.6.20
cffi==1.14.2
click==7.1.2
click-didyoumean==0.0.3
click-plugins==1.1.1
click-repl==0.1.6
cycler==0.10.0
Django==3.1.4
django-braces==1.14.0
django-celery-beat==2.1.0
django-common-helpers==0.9.2
django-cron==0.5.1
django-crontab==0.7.1
django-debug-toolbar==2.2
django-timezone-field==4.1.1

... and the list goes on.

Can somebody please help me discover the issue behind this? Thank you!

I also met this. Even though haven't solved this, I found it should be a version or package conflict. I tried but didn't find compatible versions of them(django celery celery-beat-beat, maybe etc.)

Then I discard the 'django_celery_beat' from the INSTALLED_APPS. Anyway, it works.

If you have a better solution, please tell us.

For me the problem was with the python version: django_celery_beat was installed on python3.9 site-packages and pip was using python3.8 site-packages.

try:

python -m pip install django-celery-beat

and then:

INSTALLED_APPS = [
....,
'django_celery_beat',
]

then migrate:

python manage.py makemigrations
python manage.py migrate

django_celery_beat must be before Data_Science_Web_Appin INSTALLED_APPS

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django_celery_beat',
    'Data_Science_Web_App',
]

I had this problem too, but then I found that I didn't put a comma after I added "django_celery_beat" to INSTALLED_APPS
