The Django 1.11.19 .whl release file appears to erroneously contain a file that appears to be from the 2.x release (it contains Py3 only code).
The file in question is django.contrib.admin.templatetags.base which shouldn't exist in the 1.11.19 release. This file doesn't appear to exist in the .tar.gz file. I'm downloading from https://pypi.org/project/Django/1.11.19/#files and the link for the bad .whl is https://files.pythonhosted.org/packages/6b/2a/6625366e0e26fcc638c76d1a8b63d8d24a99d129cfebf8b101aaab0327fd/Django-1.11.19-py2.py3-none-any.whl -- You received this message because you are subscribed to the Google Groups "Django users" group.
