[MM3-users] django 2.2.5 which is incompatible

Hi,

On Debian, in the process of setting up Mailman 3.3.0 I'm getting:

$ pip3 install postorius ... django-mailman3 1.3.0 has requirement Django<2.2,>=1.11, but you'll have django 2.2.5 which is incompatible. ... Successfully installed Django-2.2.5 ...

Which may or may not be causing a later error when creating superuser:

ImportError: No module named django.core.management

Am I missing the obvious somewhere?

Thanks, Mark
