Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found some lint.

Here's what I've got...

For recipe/meta.yaml:

• noarch: python recipes are required to have a lower bound on the python version. Typically this means putting python >=3.6 in both host and run but you should check upstream for the package's Python compatibility.

For recipe/meta.yaml:

• No valid build backend found for Python recipe for package executor using pip. Python recipes using pip need to explicitly specify a build backend in the host section. If your recipe has built with only pip in the host section in the past, you likely should add setuptools to the host section of your recipe.
• PyPI default URL is now pypi.org, and not pypi.io. You may want to update the default source url.
