Hi there 👋

If I want to install hf-transfer (0.1.6) in a venv with Python 3.9.19 I have such an error:

Collecting hf-transfer
  Using cached hf_transfer-0.1.6.tar.gz (22 kB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... done
  Preparing metadata (pyproject.toml) ... error
  error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

If I do the same with Python 3.8, 3.10, 3.11 or Python 3.9 but hf-transfer==0.1.4 I don't have any issue.

Reproduction

1. Create a venv with Python 3.9.19
2. pip install hf-transfer

Expected behavior

Installation doesn't build a wheel, but rather installs a pre-build one.
