While the docs at
https://docs.djangoproject.com/en/3.2/topics/serialization/#serialization-
formats do mention that PyYAML is required for the yaml serializer,
`./manage.py dumpdata|loaddata --format yaml`, provides quite a sparse
error message, "Unable to serialize database: module yaml not found" (from
here:
https://github.com/django/django/blob/fbb1984046ae00bdf0b894a6b63294395da1cce8/django/core/management/commands/dumpdata.py#L245)
if PyYAML is not installed.
This could be especially confusing for new Django developers who are not
aware that `yaml` is pointing to the PyYAML project on PyPI and is not a
part of Django. Since yaml is the only one of the four serializers
requiring an add-on third party package, it may be helpful to provide a
more verbose error in this case.
