Help for LookupError: setuptools-scm was unable to detect version for

[maxschulz-COL]

Hey guys,

I am trying to implement hatch-vcs but seem to be missing something to make it work. I get the following traceback when running the command hatch version:

Traceback (most recent call last):

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

I have added

[build-system]
requires = ["hatchling","hatch-vcs"]
build-backend = "hatchling.build"

to the pyproject.toml

and

[version]
source = "vcs"

[build.hooks.vcs]
version-file = "src/vizro/_version.py"

to the hatch.toml

Am I missing something? Sorry to ask here, I could not figure out a solution so far (new to version determination via VCS!)

This issue: https://github.com/pypa/setuptools_scm/issues/278 seems to suggest something about .git being at a different level than the setup.py (or pyproject.toml I suppose) - could the reason be that I am trying to implement this on a monorepo?

Any help would be much appreciated!
