Failed to build wheel on pypi package

[ferreirajoaouerj]

Thank you for this amazing project. I'm starting to port my previous setup of pip + conda to Pixi and it was all doing well until a certain point. Here is my minimal pyproject.toml:

[project]
name = "X"
requires-python = ">= 3.12"

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

[tool.pixi.project]
channels = ["conda-forge"]
platforms = ["win-64", "linux-64", "osx-64"]

[tool.pixi.dependencies]
loguru = ">=0.7.2,<0.8"

[tool.pixi.pypi-dependencies]
geojsoncontour = ">=0.4.0, <0.5"

When I do pixi install I get the following:

pixi install
  x failed to solve the pypi requirements of 'default' 'linux-64'
  `-> Build backend failed to build wheel through `build_wheel` (exit code: 1)

The weird thing is that if I keep either one of the packages loguru or geojsoncontour the install succeeds. Keeping both packages produces the error shown above.

Seems like it's trying to build contourpy from source, which is probably unwanted this can be caused by a constraint introduced by the conda version of loguru.

Would need to dive in to know more :)

Scratch that, I think it's a pixi bug, should be fixed in the next release :)
