environment fails to find system-site-packages

[jnikula]

My project uses libclang and its python bindings. These need to be installed via the distro's package manager; the clang bindings on pypi aren't official, nor are they guaranteed to be compatible with the libclang installed. So I rely on the system site packages. (On Debian, they all get installed via apt install python3-clang.)

I've used this, and it has worked fine:

python3 -m venv --system-site-packages .venv
. .venv/bin/activate
pip install --requirement requirements.txt --upgrade
pip install --config-settings editable_mode=strict --editable .
pytest -n auto

However, my attempts at getting this to work with hatch environments have been unsuccesful.

[tool.hatch.envs.default]
system-site-packages = true
upgrade = true

[tool.hatch.envs.test]
dependencies = [
    "pytest",
    "pytest-cov",
    "pytest-xdist",
    "strictyaml",
]

[tool.hatch.envs.test.scripts]
run = "pytest -n auto"

The requirements.txt file contains pretty much the same stuff as [tool.hatch.envs.test], in particular clang isn't mentioned there. It's supposed to come from the system.

However, hatch run test:run fails to find the clang package.

Any clues on how to debug this or make it work?

How was Hatch installed?

@ofek Any further questions, things to try?

Does it work if you use the version of Hatch that your distribution provides?

AFAICT Debian doesn't provide Hatch via apt.
