Define dependencies conditioned on Python version in pixi.toml?

[MatthewSZhang]

In pyproject.toml, we can define the build dependencies like below

[build-system]
requires = [
    "scikit-learn>=1.6.0",
    "meson-python>=0.18.0; python_version > '3.9'",
    "Cython>=3.1.0; python_version > '3.9'",
    "meson-python==0.16.0; python_version == '3.9'",
    "Cython==3.0.10; python_version == '3.9'",
]
build-backend = "mesonpy"

But in pixi.toml, can we define dependencies conditioned on Python version?

Currently I use feature.py39.dependencies to overwrite the default.dependencies, like below

[dependencies]
python = ">=3.9"
scikit-learn = ">=1.6.0"
cython = ">=3.0.10" # build dependencies
meson-python = ">=0.16.0" # build dependencies

[feature.py39.dependencies]
python = "==3.9.0"
scikit-learn = "==1.6.0"
meson-python = "==0.16.0"
cython = "==3.0.10"
