failed to solve: executor failed running [/bin/sh -c pip install -r requirements.txt]: exit code: 1

This is the output from doing manage up on https://github.com/wip-abramson/aries-acapy-fullstack-starter . The docker build seems to be cycling through all the gunicorn versions it can find and rejecting all of them. This is, I assume, due to the requirements.txt not specifying a version.

This is the output of a 'normal' pip install of gunicorn.

Here's a screen dump of the text shown in the inital part of this gist, it may be a little easier ...

Tried to replicate this by making a mini project using gunicorn and, when cloning it, removing the version from gunicorn requirement in requirements.txt. However this didn't result in anything abnormal occurring ...

There's a question/answer here https://stackoverflow.com/a/49287903 which provides quite a good setup if you a test of https://github.com/shearichard/python-docker-gunicorn-weirdness was going to be done.

For ease of reference here are the Dockerfile and requirements.txt from the part of the original project which was causing problems .
