uv sync --no-source breaking from 0.4

[lambda-science]

Hello,

My basic TOML:

[project]
name = "pythia-streamlit"
version = "0.4.0"
dependencies = [
    "numpy",
    "pythia-client>=0.6.3",
]
requires-python = ">=3.12"

[tool.uv.sources]
pythia-client = { workspace = true }

[tool.uv.workspace]
members = [
    "../pythia-client"
]

In UV 0.3.5 this worked for me:

COPY --from=ghcr.io/astral-sh/uv:0.3.5 /uv /bin/uv
ENV UV_COMPILE_BYTECODE=1
ENV UV_NO_CACHE=1
ENV PATH="/code/.venv/bin:$PATH"
# Install dependencies
WORKDIR /code
COPY pyproject.toml /code/
RUN uv sync --no-install-project --no-sources

docker build .
Output: [+] Building FINISHED

In UV 0.4.13 it doesn't work anymore:

COPY --from=ghcr.io/astral-sh/uv:0.4.13 /uv /bin/uv
ENV UV_COMPILE_BYTECODE=1
ENV UV_NO_CACHE=1
ENV PATH="/code/.venv/bin:$PATH"
# Install dependencies
WORKDIR /code
COPY pyproject.toml /code/
RUN uv sync --no-install-project --no-sources

Output:

My setup is a workspace with 3 parts: two app (pythia-streamlit, pythia-api) and a python package (pythia-client). The Dockerfile snippet is coming from production image where I want to install pythia-client from Pypi. In local developement environnement I remove the --no-sources to install from local folder (from parent directory).

The update from 0.4 broke by CI/CD pipeline, because the image would not build anymore due to the error above.
Any idea why ?

[charliermarsh]

Hmm... I guess we should allow this when running with --no-sources? \cc @zanieb @konstin

[konstin]

This is a complicated one, because --no-sources should take the package from pypi (behaving as if it were a published package), so in this case, we should re-lock with the pypi version of the dep?

[zanieb]

Yeah this seems like a bug? We should not be trying to use the source entry from the lockfile when --no-sources is provided right? Roughly agree with what @konstin is saying.

At the very least, the error message is horrible. What's the suggestion if we were to keep the existing behavior and just improve the error? To run uv lock --no-sources first?

[charliermarsh]

I think there's a bug because we shouldn't even be trying to resolve the sources here (which is where the failure happens).

Im on uv 0.4.15 and I am having the same problem

Weirdly the uv sync works, it is when it goes to the next RUN command that it fails

[charliermarsh]

You'd have to pass --no-sources to each command (uv run --no-sources). We do not store sync "state" across commands.

ah okay, thank you for the quick reply <3
