I’ve noticed the last couple releases I’ve tried to make for some packages that use the “pypi” provider deployment are failing on Windows (and Windows only) with:
failed to deploy -z was unexpected at this time. Couldn't install pip, setuptools, twine or wheel.
This looks like it must be a flag that the deployment tools are adding. An example failing build: https://travis-ci.org/pytroll/pycoast/jobs/621782819
Any ideas what’s going on?
