Failed to parse pyproject.toml when I change its location

[mpizenberg]

pip-compile fails to parse my pyproject.toml when I change its location. The following pyproject.toml works fine with pip-compile when I’m in the ..../ids-peak-python/ directory, but when I create a new project at ..../controllable-leds/client/, and I copy that same pyproject.toml there, pip-compile does not work anymore.

It’s really mysterious and I was hoping someone has a clue on what’s going on.

[project]
name = "ids-peak-python"
version = "0.1.0"
description = 'Example IDS camera usage in python'
readme = "README.md"
requires-python = "==3.10.*"

dependencies = [
  "wincertstore ; platform_system == 'Windows'"
]

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

Environment Versions

1. OS Type: Windows
2. Python version: $ python -V: 3.10.10
3. pip version: $ pip --version: 23.0.1
4. pip-tools version: $ pip-compile --version: 6.12.3

Steps to replicate

1. copy the pyproject.toml in a new folder
2. run pip-compile in the folder

Expected result

It should resolve and generate the requirements file

Actual result

Installing packages in isolated environment... (hatchling)
Getting dependencies for wheel...
Getting metadata for wheel...
Backend subproccess exited when trying to invoke prepare_metadata_for_build_wheel
Failed to parse C:\Users\MatthieuPIZENBERG\git\controllable-leds\client\pyproject.toml

Is there a README.md in the new folder as well?

That was it 🤦

Thanks @AndydeCleyre ! I guess the error message could be improved

[AndydeCleyre]

Yes, definitely can be improved. I think we're waiting on new releases from other projects so that we can preserve clearer error messages. Some more info in #1711
