Summary

I tried to install a vendored version of pyfory from a personal R2 bucket, which I created a pre-signed HTTP URL of, since R2 is not supported. The error I received was

error: Failed to parse file extension; expected one of: `.whl`, `.tar.gz`, `.zip`, `.tar.bz2`, `.tar.lz`, `.tar.lzma`, `.tar.xz`, `.tar.zst`, `.tar`, `.tbz`, `.tgz`, `.tlz`, or `.txz`
  Caused by: `.whl`, `.tar.gz`, `.zip`, `.tar.bz2`, `.tar.lz`, `.tar.lzma`, `.tar.xz`, `.tar.zst`, `.tar`, `.tbz`, `.tgz`, `.tlz`, or `.txz`
