Following the general guidelines for publishing, and using Mapbox pypi account credentials, we can make new versions of rio-color available on pypi. This approach replaces our previous use of TravisCI and Appveyor, both now deprecated with our organization.
python3 -m pip install build twine
python3 -m build --sdist
python3 -m build --wheel
Once you've configured .pypirc with the project token, you can upload the packages to pypi.
twine upload dist/* --repository rio-color
And confirm the upload at the project page.
