I've a Django project running on AWS with Django1.11 and Python 2.7.
I am upgrading it to Django 2.2 and Python 3.6
I have it running locally and all tests pass. I am not trying to load it onto an AWS elasticbeanstalk instance.
When I do eb deploy, I am getting the following error in the eb activity log

The Python2.7 version was using enum34 (in requirements.txt) which I've deleted/uninstalled so I don't believe that is the issue.
I also do not understand why I'm getting the line File "/usr/lib64/python2.7/subprocess.py", line 190, in check_call
raise CalledProcessError(retcode, cmd). Why would it be trying to use Python2.7 - what haven't I amended that I should?
Can anyone help?
NOTE
Although this is the same error Why Python 3.6.1 throws AttributeError: module 'enum' has no attribute 'IntFlag'?, it doesn't help me solve on AWS through the eb deploy process
