[Build issue] Wheel fails to build on Python 3.13

[VaZark]

When using pip wheel --no-cache-dir "uvloop (==0.19.0)"

For context, I was installing uvloop as a dependency for a Robyn-based project using poetry. When it failed, I tried using a wheel directly with pip

The pyproject.toml

name = "robyn-router"
version = "0.1.0"
description = ""
authors = [
    {name = "vaz",email = "vasanth93067@gmail.com"}
]
readme = "README.md"
requires-python = ">=3.13, < 4.0.0"
dependencies = [
    "robyn (>=0.66.2,<0.67.0)"
]


[build-system]
requires = ["poetry-core>=2.0.0,<3.0.0"]
build-backend = "poetry.core.masonry.api"

It works with the latest version. Sorry for the noise
