This seems to be a very common, possibly involving a conflict between Python 2.x and Python 3.x libraries. For instance, this answer suggests the problem is with the path:
Import Python module fails (http.cookies)
but the full error that I get is:
ImportError: cannot import name 'cookies' from 'http' (/usr/local/lib/python3.7/site-packages/gunicorn/http/__init__.py)
and if I do this:
cat /usr/local/lib/python3.7/site-packages/gunicorn/http/__init__.py
I see:
# -*- coding: utf-8 -
#
# This file is part of gunicorn released under the MIT license.
# See the NOTICE for more information.
from gunicorn.http.message import Message, Request
from gunicorn.http.parser import RequestParser
__all__ = ['Message', 'Request', 'RequestParser']
So clearly, for the version of HTTP that I have, there is no cookies module exported.
If I do this:
find /usr/local/lib64/python3.7/site-packages/ -name cookie.py
I see two entries:
/usr/local/lib64/python3.7/site-packages/django/contrib/messages/storage/cookie.py
/usr/local/lib64/python3.7/site-packages/django/http/cookie.py
This file:
/usr/local/lib64/python3.7/site-packages/django/http/cookie.py
starts with:
from http import cookies
Does it make sense that this can import from itself from http, when it lives in http? And http does not export this in its __init__.py file?
UPDATE:
If I run this:
/usr/local/lib/python3.7/site-packages/gunicorn/gunicorn ecommerce.wsgi:application --bind 0.0.0.0:8000
This is the full stacktrace that I see:

This is a file that I created based on a different Stackoverflow answer:
/usr/local/lib/python3.7/site-packages/gunicorn/gunicorn
The contents of this file are:

If I do this:
