How to set dynamic version for tool.setuptools_scm in pyproject.toml

I'm trying to test the pyproject.toml by building an example.

If I deleted the line "[tool.setuptools_scm]", the build will success, but adding that line, the build will fail with the following error.

Here is the pyproject.toml: /test/example/pyproject.toml

[project]name = "example"dynamic = ["version"][tool.setuptools.dynamic]version = {attr = "example.__version__"}[tool.setuptools_scm]

When building with this command:

# cd /test/example# python -m build --no-isolation

Here is the error:

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=projERROR Backend subprocess exited when trying to invoke get_requires_for_build_sdist

What's the correct configuration for [tool.setuptools_scm] in pyproject.toml?
