SyntaxError: invalid syntax

[abhinavsingh]

Write to now seems to be producing invalid python files:

_scm_version.py", line 6
    __version__ : str = version : str = '1.3.0rc9.dev290+g7dce6a7'
                                ^
SyntaxError: invalid syntax

Previously we used to see

# coding: utf-8
# file generated by setuptools_scm
# don't change, don't track in version control
version = '1.3.0rc9.dev289+g7451c8a.d20230920'
version_tuple = (1, 3, 0, 'dev289', 'g7451c8a.d20230920')

which then changed to:

# file generated by setuptools_scm
# don't change, don't track in version control
__version__ = version = '1.3.0rc9.dev289+g7451c8a.d20230920'
__version_tuple__ = version_tuple = (1, 3, 0, 'dev289', 'g7451c8a.d20230920')

but since TODAY , we are seeing inclusion of typing syntax in generated files, leading to our workflow failures. I tried to reproduce locally without any luck, on my local I don't see any typing information in generated files.

Workaround

Pin to setuptools-scm[toml] == 7.1.0

This is a duplicate of #905

But we are seeing this for python > 3.8
