python3-setuptools-scm-opt (setuptools-scm installed to /opt)
setuptools_scm extracts Python package versions from git or hg
metadata instead of declaring them as the version argument or in a SCM
managed file.
# Build your package with this version to fix errors like the following:
ImportError: cannot import name '__version__' from ...
NOTE:
Installs to /opt/python$PYVER/site-packages
Add the following before the python3 build commands in your
Slackbuild to use this version over the stock one in 15.0:
PYVER=$(python3 -c 'import sys; print("%d.%d" % sys.version_info[:2])')
export PYTHONPATH=/opt/python$PYVER/site-packages
