Packages that fail to install under PEP 517 with build isolation

I don't know that an issue is the right home for this, but I want to track the packages we know can't be installed under PEP 517 when build isolation is enforced. In all cases, these packages also fail under pip install --use-pep517.

This also causes ViTPose to fail.

@baggiponte -- I think you need to install wheel as well -- that's the trace you get when you're missing wheel (e.g., uv pip install wheel).

@baggiponte -- I think you need to install wheel as well -- that's the trace you get when you're missing wheel (e.g., uv pip install wheel).

That solves it - then I get weird C errors but definitely not uv-related.

Do you think uv should automatically recommend this kind of suggestions? A bit like the Rust compiler, that has wonderfully helpful error messages.

Yeah we should add a nice message for “missing wheel”. We have that for a few other failures. \cc @konstin

cchardet which doesn't work on Py311 out of the box, but does work on Py311 with cython installed.

~~But pip --pep517 still works, uv doesn't (maybe because the package has no pyproject.toml?)~~

$ uv venv .venv --seed
$ .venv/bin/pip install cython==3.0.0
$ .venv/bin/pip install cchardet==2.1.7 --use-pep517

~~succeeds~~ fails with a cold cache. Succeeds without --use-pep517. then uv:

$ uv venv .venv
$ uv pip install --python .venv/bin/python cython==3.0.0
$ uv pip install --python .venv/bin/python cchardet==2.1.7

fails.

~~LMK if, because pip does handle this, it belongs in a new issue~~

pip install cchardet==2.1.7 --use-pep517 does not work for me actually.

Ahhhhhhh I'm like 90% certain pip pulled it from its cache on my box. 😅

EDIT: Yeah this fails: .venv/bin/pip install cchardet==2.1.7 --use-pep517 --no-cache

Is the solution to just pip install?

@amanmibra -- The solution is generally to do something like:

uv venv
uv pip install torch setuptools
uv pip install --no-build-isolation ${package}

I.e., you create a virtual environment, "manually" install any build dependencies, then install the package in question with --no-build-isolation, so that it's built in your virtual environment and has access to the installed dependencies.

What's the uv logic for building packages with no pyproject.toml? (asking in light of #5551 - wondering if uv should just assume a very specific old version of setuptools... I don't know what pip does)

@astrojuanlu The default backend is defined here:

uv/crates/uv-build/src/lib.rs

Lines 69 to 76 in 194904b

    
           /// The default backend to use when PEP 517 is used without a `build-system` section. 
        
           static DEFAULT_BACKEND: LazyLock<Pep517Backend> = LazyLock::new(|| Pep517Backend { 
        
               backend: "setuptools.build_meta:__legacy__".to_string(), 
        
               backend_path: None, 
        
               requirements: vec![Requirement::from( 
        
                   pep508_rs::Requirement::from_str("setuptools >= 40.8.0").unwrap(), 
        
               )], 
        
           });

@charliermarsh Is there a similar workaround for uv pip compile? I landed here by googling error when trying to install torch and trorch-cluster. Am I supposed to put torch in the requirements.in, and then install from the output requirements.txt + torch-cluster ?

# requirements.in
foo
bar
...
torch

$ uv pip compile requirements.in --output-file requirements.txt
$ uv pip sync requirements.txt
$ uv pip install torch-cluster

	backend: "setuptools.build_meta:__legacy__".to_string(),
	backend_path: None,
	requirements: vec![Requirement::from(
	pep508_rs::Requirement::from_str("setuptools >= 40.8.0").unwrap(),
	)],
	});
