It is if you build from a PyPI archive, which has some metadata
available. If you build from a git checkout, it expects to compute/find
the version from git, and won't be able to do so in Guix (.git is
stripped for reproducibility). In this case, you must set
SETUPTOOLS_SCM_PRETEND_VERSION, e.g. as done in python-scanpy:
--8<---------------cut here---------------start------------->8---
(add-after 'unpack 'pretend-version
(lambda _
(setenv "SETUPTOOLS_SCM_PRETEND_VERSION" #$version)))
--8<---------------cut here---------------end--------------->8---
See also the relevant issue/feature request https://issues.guix.gnu.org/54899 I
had
reported a long time ago.
Hope that helps,
