Unable to pip install on macos

[IanWhalen]

Similar to #12 , has anyone else run into trouble installing this library on macos? M1 chip with macos 13.5.1.

I'm trying to my development locally and then actually run on a raspberry pi, but running poetry add rpi-ws281x gives me:

    note: This error originates from a subprocess, and is likely not a problem with pip.
    ERROR: Failed building wheel for rpi-ws281x

same error with plain old pip install rpi-ws281x.

I'm not seeing why sysmacros.h should be missing or any indication that its a linux-specific file, so I assume I should be able to install?

You'd need stubs or a dummy library for this. Installing on anything but a Pi is very much out of scope.

ok, thanks for the clarification.
