Thanks Steve,
Below is the results from following your steps. I started clean with the
sample application, not my app.

[ec2-user@ip-172-31-28-79 bin]$ /usr/bin/python --version

> * Create a virtual environment inside your user home directory.
[ec2-user@ip-172-31-28-79 bin]$ cd
[ec2-user@ip-172-31-28-79 ~]$ export VENV=${PWD}/env
[ec2-user@ip-172-31-28-79 ~]$ python3 -m venv $VENV
Error: Command '['/home/ec2-user/env/bin/python3', '-Im', 'ensurepip',
'--upgrade', '--default-pip']' returned non-zero exit status 1
Again, no pip, so executing
> $VENV/bin/pip install --upgrade pip setuptools
yields the following
[ec2-user@ip-172-31-28-79 ~]$ $VENV/bin/pip install --upgrade pip setuptools
-bash: /home/ec2-user/env/bin/pip: No such file or directory
However, I will note that we can create custom environments, so maybe this
is the key. Whatever AWS is using for python (which I imagine is for flask
and django) has been tailored for that. They also say you can also use
Ubuntu or RHEL. I am thinking that a custom environment is needed with a
proper python3 install.
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/custom-platforms.html
Anyway, I will try to work on this a bit later. I just wanted to report
back asap.
Thanks
