ERROR: Cannot install -r requirements.txt (line 15), -r requirements.txt (line 17) and djangorestframework==3.11.2 because these package versions have conflicting dependencies.
#0 41.92
#0 41.92 The conflict is caused by:
#0 41.92 The user requested djangorestframework==3.11.2
#0 41.92 django-rest-auth 0.9.5 depends on djangorestframework>=3.1.3
#0 41.92 djangorestframework-simplejwt 5.3.1 depends on djangorestframework>=3.12
#0 41.92
#0 41.92 To fix this you could try to:
