ModuleNotFoundError: No module named 'six'

[efung]

I'm trying to set up a brand new Python based project, and have a minimal dev environment right now, just Python 3.8.4 and pip.

After adding this to my requirements.txt:

git+https://github.com/Shopify/[email protected]

I did dev up, and saw the package being installed.

I then added this entry to dev.yml:

commands:
    lint:
        desc: Highlight syntactical and stylistic problems in the code via pylint
        run: "pylint --rcfile=pylintrc package tests *.py"

But when I run dev lint, I get this missing module error. Does the six module need to be declared in shopify_python's setup.py?

For context, I'm trying to document how to set up a Python project from scratch, that can be deployed on our Production Platform. Currently, there are no walkthroughs in their docs for Python.

I want to include the Shopify Python standards, but it looks just installing the current module doesn't quite work out of the box, due to this issue, as well as the issue with the pylint version
