Impossible to add a pypi git dependency in a clean environment

[akhmerov]

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

[project]
authors = ["Anton Akhmerov"]
channels = ["conda-forge"]
description = "Can't boostrap pypi git dependency"
name = "pixi_bug"
platforms = ["linux-64"]
version = "0.1.0"

[tasks]

[dependencies]
python = ">=3.13.0,<3.14"
git = ">=2.47.1,<3"

[pypi-dependencies]
skunk = { git = "https://github.com/akhmerov/skunk.git" }

Issue description

It is impossible to install a git dependency in a pixi environment without git even if git is available via pixi itself.

Expected behavior

Pixi should be able to use git to install pypi dependencies from git sources just like it uses python.

I don't have a clean environment to fully test this on, but I think (assuming aliasing git to no-op on my machine worked), you can change your manifest to:

....
[host-dependencies]
git = ">=2.47.1,<3"

[dependencies]
python = ">=3.13.0,<3.14"

[pypi-dependencies]
skunk = { git = "https://github.com/akhmerov/skunk.git" }

I was able to get a isolated linux vm with no git available, and I was wrong. I get the same error if git is in dependencies, host-dependencies or build-dependencies. On my laptop, it seems like it was find a system git install even though I thought they had all been disabled:
