Bug? Can't run uv sync on package with --no-build

[Chasarr]

When trying to create a new package with say uv init --package, add a dependency, say the progress package, with uv add progress. My pyprojects.toml looks like this:

[project]
name = "hatch-demo"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
authors = [
    { name = "My Name", email = "[email protected]" }
]
requires-python = ">=3.12"
dependencies = [
    "progress>=1.6",
]

[project.scripts]
hatch-demo = "hatch_demo:main"

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

Company policy is to ensure that we don't use source distributions (only prebuilt binary wheel dependencies) which we used to do with pip install -r requirements.txt --no-compile. We are now trying to switch over to uv, but uv sync --no-build returns
error: Distribution hatch-demo==0.1.0 @ editable+.can't be installed because it is marked as--no-build but has no binary distribution

Although I can see why this returns an error, the purpose of --no-build for us should be to not build dependencies when building our package, not to inhibit us from building the package itself. We could technically do uv sync --no-build-package pkg1 --no-build-package pkg2 ... --no-build-package pkgN for all dependencies, but that doesn't seem like a very elegant solution.

Not sure if a fix for this problem aligns with the goals of uv.

TLDR: I want to 1) uv sync dependencies with --no-build and then 2) build the package with said dependencies.

I would suggest uv sync --no-build --no-install-project to skip building and installing hatch-demo.

Thanks for guiding me to the right answer! To avoid running build on packages in my CI environment, I just enter

uv sync --no-build --no-install-project # Fetches prebuilt wheels
uv sync --frozen # builds project with previously synced dependencies
uv run --frozen <MY_PACKAGE> # Now CI can perform tests on the package before publishing to internal Python package index

Thanks a lot!

No worries! Thank you for following up.
