In the latest version (5.5.1), rest_framework_simplejwt/settings.py unconditionally imports setting_changed from django.test.signals.
In many production environments or Docker builds using package managers like Poetry with the --without test flag, the django.test module is not installed. This causes the application to crash on startup during the Django setup phase.

ModuleNotFoundError: No module named 'django.test'Environment:
Python: 3.13 (or any version where django.test is excluded)
Django: 5.1+
djangorestframework-simplejwt: 5.5.1
Installation Method: poetry install --without test
Suggested Fix:
The import should be wrapped in a try...except block or moved to a location where it is only called during testing. Alternatively, it could be imported from django.core.signals if applicable, as setting_changed is also available there in modern Django versions.
