Issue description

pixi fail to resolve pypi dependencies by version, but it will succeed when by path

Additionally, I successfully installed this package by [email protected].

Expected behavior

Can successfully resolve pypi dependencies through version

I think this again has to do with the system-requirements. Could you try with:

[system-requirements]
libc = "2.31"

I personally can not recreate this issue as I can't seem to find the package at all.

[zen-xu]

Still doesn't work.

Is there a way to get alpha-flow2 for me?

[zen-xu]

Sorry, this is a private package, but I will continue to investigate. At present, I found that the UV only detects the wheel of py311, and does not detect the wheel of py37, resulting in the inability to install py37.

selfhost pypi index returns

• alpha-flow2.py311.wheel
• alpha-flow2.py37.wheel

I guess whether the UV matches the package of the first wheel and then doesn't match any further.

I've found the reason. The default value for default_glibc_version is 2.17, which causes the largest manylinux not to be less than it. However, the package I installed requires 2.31.

So I just need to specify system-requirements libc = "2.31"

I'm sorry for my typo, I did indeed mean libc with my system-requirements example. Thanks for the full answer!
