so uv ends up marking some version as compatible even though it doesn't have a wheel for the platform where it's running the resolution (macOS arm64). Is it a coincidence that it's showing another macos wheel (cp311-macosx_10_9_x86_64) as evidence for compatibility ? is this a bug, or a limitation of universal resolution ? In the latter case, is there a more elegant workaround than bumping my minimal requirement or adding a constraint ?

In this case, you need to set
tool.uv.required-environmentsto your macOS arm64 environment (https://docs.astral.sh/uv/concepts/resolution/#required-environments).no-build-packageinfluences the resolution foruv pip install, but can't influence the universal resolution foruv sync, which needs to be independent of the platform where uv is currently running on. Usually we show a hint fortool.uv.required-environments, but it looks like the--no-buildhint takes precedence.neutrinoceros commentedon Oct 8, 2025
excellent, thank you ! Indeed I didn't know about
required-environmentsand that's exactly what I needed. Hopefully it's possible to make the logs point to it.
