(no pipenv support as it can't install)

[mcallaghan-bsm]

we are definitely lacking useful error message here;

For some reason pipenv doesn't like it when Pipfile is in the root dir /Pipfile

If I do things a bit differently (create a sub-dir outside of the root), it works

$ docker run -it python:3-slim bash -c "pip3 install --upgrade pip; pip3 install pipenv; mkdir /app; cd /app; pipenv install pylint"
