Why can't connect djongo as a backend?

Question

Django

Configured the database in the settings:

# settings.py
DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'django-db',
    }
}

Installed all required packages:

installed packages

asgiref==3.5.0
Django==4.0.2
djongo==1.3.6
pymongo==4.0.1
sqlparse==0.2.4
tzdata==2021.5

When trying to perform any action (starting the server / migration / etc), an error pops up:

Answer 1

First of all, check what version of django this djongo supports, the error hints that it can’t do
PS 4, although it might be enough to install pytz
