pip-compile fails with version settings in setup.cfg

[Thomasillo]

Environment Versions

1. OS Type Windows10
2. Python version: 3.7.12
3. pip version: 21.3.1
4. pip-tools version: 6.4.0

Steps to replicate

# setup.cfg
[metadata]
name=Thing
version = attr: Thing.__version__
[options]
install_requires = 
    requests

#setup.py
import setuptools
setuptools.setup()

# Thing/__init__.py
__version__ = "1.0.0"

Then run

$ pip-compile

Without the line
version = attr: Thing.__version__ it works.

Expected result

No error, a valid requirements.txt file

Could you try pip install -e .?

[Thomasillo]

That seems to work.

I'm also using setup.cfg in my projects but I can't reproduce this. I tried to make something exactly like your project. This is the tree output:

$ tree -L 2
.
├── python_packages
│   ├── bin
│   ├── lib
│   └── pyvenv.cfg
├── setup.cfg
├── setup.py
└── Thing
    └── __init__.py

4 directories, 4 files

I'm using Python 3.9 with the following packages:

Package    Version
---------- -------
click      8.0.3
pep517     0.12.0
pip        21.3.1
pip-tools  6.4.0
setuptools 59.2.0
tomli      1.2.2
wheel      0.37.0

I'm also unable to reproduce this, but I'm only testing with linux.

Are you still able to reproduce, @Thomasillo? With either those versions, or updated pip-tools?

[AndydeCleyre]

@Thomasillo

Hello! It's been a while since you first encountered this. Are you still able to reproduce the problem?

If not, it may be time to close this one.

Thanks!

@Thomasillo

Please comment here with an update if you can still reproduce this, and I'll re-open, but for now I'm going to close this.

Thanks!
