uv.lock generated with uv==0.5.18 fails to parse in uv==0.5.19

error:

error: Failed to parse `uv.lock`

repro:

[project]
name = "uv-test"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = ["watchdog==6.0.0"]

command rm uv.lock && pip install uv==0.5.18 && uv lock && pip install uv==0.5.19 && uv lock

running rm uv.lock && pip install uv==0.5.19 && uv lock is successful <=== This is the workaround (delete and regen the lockfile)

Makes sense, thanks.

We are running into the same issue with uv 0.5.19 with both watchdog and pycryptodome as another data point

Command: uv sync --frozen --no-dev

Looks like this was already somewhat identified: https://github.com/astral-sh/uv/blob/main/crates/uv-resolver/src/lock/mod.rs#L308

// TODO(charlie): This omits win_ia64, which is accepted by Warehouse.

[charliermarsh]

Omitting the tag is fine — we never supported it, so uv never would’ve selected it. The problem here is just that we can’t deserialize it from an existing lockfile.

[zanieb]

If you delete the entry from the lockfile, it should solve the problem without any other effect (since, as Charlie said, we don't support selecting those wheels anyway).

We'll see if there's a reasonable way to support deserializing unknown tags from existing lockfiles.

[charliermarsh]

I'll try to fix this now, sorry.

Hitting this as well, broke on CI (using a python:3.12 image) as it pulled the latest uv version:

[charliermarsh]

Can you please include the error message for my own records?

done :)

#10655 is up which fixes this; we'll have a release out once it's merged.

[sunshowers]

Thanks for the easy workaround btw! Removing the win_ia64 wheel was quite easy.

[charliermarsh]

Thanks for confirming @sunshowers and sorry for the disruption.
