The problem is that the workflow environment is not getting the proper version number from the package.

I definitely remember a similar problem cropping up somewhere else, but I can't remember where!

Some breadcrumbs:

• https://github.com/pangeo-forge/pangeo-forge-recipes/pull/128
• https://github.com/pangeo-forge/pangeo-forge-recipes/pull/129
• https://github.com/pangeo-forge/pangeo-forge-recipes/pull/130
• https://github.com/pangeo-forge/pangeo-forge-recipes/pull/131

I think all of those were sufficient to fix the version issue. I don’t recall what exactly was necessary. It might be worth checking if the toml package is available on GitHub actions / wherever the tag is being set first.

Cool. One thing you can do while debugging the CI is to make a bunch of “release candidate” (RC) releases, rather than continuing to bump the version.
