I have no idea what you were trying to do. I'd need more information in order to give a somewhat useful answer.

Works for me.

In any case:

1. Please check out the Installation instructions for pytest-dependency.
2. whatever you want to do to install pytest-dependency, always start from the released source distribution.

Did you try to use autogenerated from git tag tar ball? 🤔

[RKrahl]

I did exactly what I wrote above: I unpacked the source distribution changed into that directory and ran python3.8 -sBm build -w --no-isolation. (You need to have build and wheel installed for this command to work.)

You still didn't tell me what you were trying to do. I suspect that you didn't start from the source distribution, but from the cloned git repository. In that case, you'd need to additionally install git-props (and the git program of course).

Do you have git matadata in that tar ball?
Autogenerated from git tag tar ball has no .git/directory.

BTW: why not use for example setuptool-scm instead setuptools + set of custom reads from git metadata? 🤔
It would allow as well significantly shorten setup.py.

[kloczek]

BTW:

pytest-dependency/setup.py

Lines 10 to 13 in 9d5e0d3

	import setuptools.command.build_py
	import distutils.command.sdist
	import distutils.file_util
	from distutils import log

distutils is already deprecated.

Next thing

pytest-dependency/setup.py

Line 162 in 9d5e0d3

install_requires = ["setuptools", "pytest >= 3.7.0"],

Looks like setuptools can be removed from that list.

[RKrahl]

In my very first comment above, I pointed you to the Installation instructions for pytest-dependency. May I suggest you to actually read that piece of documentation?

Do you have git matadata in that tar ball? Autogenerated from git tag tar ball has no .git/directory.

That tar ball is the source distribution that is supposed to be the starting point for any attempt to install pytest-dependency. And yes, it contains the relevant metadata.

BTW: why not use for example setuptool-scm instead setuptools + set of custom reads from git metadata? 🤔

I use git-props instead of setuptool-scm. It is similar, but has some advantages over the latter.

It would allow as well significantly shorten setup.py.

Bullshit!

distutils is already deprecated.

It was deprecated in the standard library and has been removed from there in Python 3.12. But it is still included in setuptools, actually, it is the basis that setuptools builds upon.

Looks like setuptools can be removed from that list.

It is required for the manual installation from the source distribution.

I repeat myself: you still didn't tell me what you were trying to do. You didn't provided any reproducible error description. I thus close as invalid.
