Good afternoon, when starting gunicorn, it gives an error:

ImportError: No module named 'django_extensions'
The bottom line is that I have django_extensions installed
Package Version
------------------------ -------
Django 2.2.1
django-ckeditor 5.7.1
django-extensions 2.1.9
Networking also has
INSTALLED_APPS = [
'jet.dashboard',
'jet',
'django.contrib.admin',
'django.contrib.auth',
'django .contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django_extensions',
Several times I already deleted and reinstalled it, updated it, even deleted the entire project with the virtual machine and re-uploaded it, still this error. Moreover, everything is fine on the local server, the error is in production.
