Thanks for the thorough report! Does this work if you use hatchling as a build backend instead of setuptools, e.g. as we do in default in uv init? I imagine this is a weird setuptools bug.

Hm, that's really interesting: it builds fine with hatchling. However, adding --no-build-package demo flag to the original uv sync command does not change anything, so the problem shouldn't be caused by building a root project.

Just for the sake of completeness, here's what does build:

--no-build-package can't be applied to local editables — just remote source distributions. I think it will be ignored.

Created an issue to improve messaging there #6446

Ough. Is there any way to spell "I don't want the root project built - please just install the dependencies as specified"?

Not yet, but probably soon — lots of discussion on that at #4028

I'd highly recommend not using setuptools in the meantime, maybe this needs to be reported there? I'm not sure without really digging in.

I'll try to debug a bit today, but this really looks like a setuptools problem - I'll report my investigation here later and close the issue if it's not on uv's side, reporting my observations to setuptools instead.

Well, sorry for spending your time - this bug has nothing to do with uv. It's caused by setuptools package discovery attempt and can be fixed with e.g.

[tool.setuptools.packages.find]
where = []

Without this, setuptools apparently try to scan the whole image's filesystem while working in /, and that is expected to take unreasonable time.
