Thanks, this worked for me. I skimmed the related bug, but missed this comment. I think the docs for pyproject-build-system are likely the best place for this, as they already mention some of the setuptools/pyproject interaction. I sent a patch (#74899) with some draft language, let me know what you think. > The python importer should probably be updated to read pyproject.toml > and parse the [build-system] table (there is a toml parser in Guix now, > so this should be easy). > Would it be helpful to open a bug about this?
