`uv pip` fails to install necessary packages

[jepler]

Board Name

Raspberry Pi 5

Steps

1. Install uv
2. uv venv /tmp/blinka-uv
3. . /tmp/blinka-uv/bin/activate
4. uv pip install adafruit-blinka
5. python -c 'import board

Description

Following these steps, the result is ModuleNotFoundError: No module named 'RPi'. Comparing uv pip freeze in this venv to pip freeze in a working venv, one can see the following two files were not installed: rpi-ws281x==5.0.0 RPi.GPIO==0.7.1

Additional information

This is likely to be related to how these declarations are conditional in the setup.py file. I couldn't find where this was a documented limitation of uv, but it seems possible/likely.

. o O ( I'm actually not sure how good old pip knows how to install RPi.GPIO when it installs a wheel of adafruit-blinka... )

just documenting that blinka & uv are incompatible is probably fine for the moment!

This is semi-related to #907 and adafruit/Raspberry-Pi-Installer-Scripts#329

I think the only way to get it working (currently) is via that installer script, which does some manual installing/removing to get things setup for Pi5. (see PR 329)

So not surprising things generally aren't working with other tooling.

This feels more like a problem with RPi.GPIO package. Its rather uncommon to have a dot in the package name. Before uv came around, I remember seeing this No module named 'RPi' error before; but it usually meant that the package RPi.GPIO wasn't installed (via apt-get).

BTW, the RPi.GPIO implementation does not work on RPi5 because the GPIO pins are abstracted to a separate RP1 chip. See ticket on sourceforge (which I think makermelissa raised).
