After djangocms-installer is installed it cannot be run because of missing pytz

[michalnik]

Description

I started new project with django-cms. I created virtualenv. I upgraded pip. I installed djangocms-installer. I run djangocms-installer and it did not turn out well.

Steps to reproduce

$ python3.7 -m venv env
$ source env/bin/activate
$ pip install --upgrade pip
$ pip install djangocms-installer
$ djangocms

Versions

python3.7 django3.1.14 djangocms-installer2.0.0

Expected behaviour

It ends with exit code 2 and caught Exception handling with this message :

djangocms: error: the following arguments are required: project_name

Actual behaviour

It ends with exit code 1 and raised Exception :

ModuleNotFoundError: No module named 'pytz'

Additional information

I don't know what else I should put here.
