Fails to build on Raspbian 13 #691
Description
I have the latest Raspbian 13 (Trixie) installed on a Raspberry Pi Zero 2 W. It is a completely fresh install, 32 bit, no desktop. It comes with Python 3.13.5 installed as default and I am unable to install uvloop with pip.
Using uv, I have also tried to install it on python 3.13.7 and 3.14 but the build fails the exact same way. On my own desktop (Kubuntu) it installs with no issues using Python 3.13.5 so it might be specific to Raspbian and/or Debian.
Defaulting to user installation because normal site-packages is not writeable

Python recognizes 'uvloop.handles' as an importable package[^1],
but it is absent from setuptools' `packages` configuration.
This leads to an ambiguous overall configuration. If you want to distribute this
package, please make sure that 'uvloop.handles' is explicitly added
to the `packages` configuration field.
Alternatively, you can also rely on setuptools' discovery methods
(for example by using `find_namespace_packages(...)`/`find_namespace:`
instead of `find_packages(...)`/`find:`).
You can read more about "package discovery" on setuptools documentation page:
- https://setuptools.pypa.io/en/latest/userguide/package_discovery.html
If you don't want 'uvloop.handles' to be distributed and are
already explicitly excluding 'uvloop.handles' via
`find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
you can try to use `exclude_package_data`, or `include-package-data=False` in
combination with a more fine grained `package-data` configuration.
You can read more about "package data files" on setuptools documentation page:
- https://setuptools.pypa.io/en/latest/userguide/datafiles.html
[^1]: For Python, any directory (with suitable naming) can be imported,
even if it does not contain any `.py` files.
On the other hand, currently there is no concept of package data
directory, all directories are treated like packages.
