running with --verbose might help there was also a bug with relative paths that was fixed in uv 0.1.2: https://github.com/astral-sh/uv/issues/1393#issuecomment-1947772947

Do you mind sharing what the requires-python values look like in the index? Like if you download one of the wheels manually, and open it, and look at METADATA, what is the requires-python? It looks like it's invalid -- we do some manual correction for common mistakes, but we might be missing one here.

We may have fixed this in #1529. Do you mind trying with latest?

[merc1031]

I can confirm the with version 0.1.7 It has solved the issue for me!
