Description Miro Hrončok 2026-04-01 12:14:47 UTC

We are trying to python-setuptools_scm to version 10.x

https://src.fedoraproject.org/rpms/python-setuptools_scm/pull-request/39


This package fails to build with:

error: Installed (but unpackaged) file(s) found:
   /usr/lib/python3.14/site-packages/VERSION

https://copr.fedorainfracloud.org/coprs/churchyard/vcs-versioning/package/flatpak-module-tools/



See https://setuptools-scm.readthedocs.io/en/latest/changelog/#1000-2026-02-26

"""
Version files (write_to and version_file) are now written to the build directory during build_py instead of the source tree during version inference. This enables installing packages from read-only source directories (e.g., Bazel builds).

Path transformation is automatically applied for src/ layouts - a configured path like src/mypackage/_version.py is correctly written to mypackage/_version.py in the build directory based on the package_dir configuration.

To restore the old behavior of writing version files at inference time (useful for development workflows), set the environment variable SETUPTOOLS_SCM_WRITE_TO_SOURCE=1. https://github.com/pypa/setuptools-scm/issues/1252

Do you need help fixing this? Please respond.

Comment 2 Miro Hrončok 2026-04-17 12:14:30 UTC

Setting SETUPTOOLS_SCM_WRITE_TO_SOURCE=1 probably makes no difference, see my upstream report https://github.com/pypa/setuptools-scm/issues/1364

For now, perhaps rm -rf after %pyproject_install is a way to go.
