Hi Skip,
One option would be to allow tox to install the package in the lint env with
`skip_install = false` (which is the default behaviour, so the skip_install
line can just be deleted). Then the "deps =" for the lint env can go back to
just pylint. It's not the most efficient, but saves on config.
I'm not so good at stuffing tox config inside pyproject.toml - but maybe
someone else has a suggestion doing that.
Cheers,
James
