Installing quadax in windows 10 with pip gives this error

ERROR: Could not install packages due to an OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: 'C:\\Users\\user\\<project_path>\\.venv\\*

while installing with uv gives this other error

  help: `quadax` (v0.2.5) was included because `dummy` (v0.1.0) depends on `quadax`

The problem seems to affect windows because it doesn't support files with asterisks. Inspecting the file quadax-0.2.5-py3-none.whl reveals that it contains data files

quadax-0.2.5.data/data/_/requirements.txt
quadax-0.2.5.data/data/_/requirements-dev.txt

while quadax-0.2.5.dist-info/RECORD refers to them in the following manner

quadax-0.2.5.data/data/*/requirements-dev.txt,sha256=f5QMec-IahYECs4OvocQWWqO2IXiwWKKNbsD7V6yoTk,556
quadax-0.2.5.data/data/*/requirements.txt,sha256=l4H4ACI11gQsGwguQ2h45GLLxTODDgyu4YbHP9_KUcE,79

Taking a look at the setup.cfg configuration of this project shows that it uses

quadax/setup.cfg

Lines 82 to 84 in 6745cb9

	[options.data_files]
	* =
	*.txt

This configuration is similar to the one proposed by setuptools, except that it's using the deprecated option data_files instead of package_data
https://setuptools.pypa.io/en/latest/userguide/datafiles.html

Also there may be some issues with data_files and asterisks on windows, see pypa/setuptools#1681.

An easy fix may be to just to remove the section options.data_files. The file requirements.txt typically doesn't need to be included inside the package, however it's not 100% clear to me how quadax is packaged.

In particular, this comment indicates a possible reason why data_files was used at some point but setuptools-declarative-requirements doesn't seem to be used anymore

quadax/setup.cfg

Lines 86 to 91 in 6745cb9

	[requirements-files]
	# setuptools does not support "file:", so use a extra package for this:
	# https://pypi.org/project/setuptools-declarative-requirements/
	# https://github.com/pypa/setuptools/issues/1951#issuecomment-718094135
	install_requires = requirements.txt
	setup_requires = requirements-dev.txt

EDIT: I realized that quadax is using the deprecated data_files option instead of package_data. This is quite likely the root of the problem.
