  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 364, in execute_from_command_line
    utility.execute()
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 338, in execute
    django.setup()
  File "/usr/local/lib/python2.7/dist-packages/django/__init__.py", line 27, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/usr/local/lib/python2.7/dist-packages/django/apps/registry.py", line 85, in populate
    app_config = AppConfig.create(entry)

Answer 1

That Python3-only open() was added with version 3.0.6. Try earlier versions, 3.0.5 or 3.0.4:

pip install django-reversion==3.0.5

or

pip install django-reversion==3.0.4

Answer 2

Django 3 supports python versions 3.6 and above.

Here is the official Django 3.0 release notes
