Build issue OSX Tahoe 26.2

[boggan]

Hi!

I'm unable to install the headless-gl package under the latest version of OSX, tried with node 24 and node 22, the error seems to come from the version of python requested for the build I think ?

anyways, I hope you can help :)

he're the build output

then I changed the environment to use python3 (which is the one installed) and here's the result

Hi! From your logs, it looks like you are trying to install/build version 3.0.7, which likely doesn't support python3, as that version of headless-gl is several years old. Please correct me if I'm wrong.

Can you try a more recent version? The v9 release candidate supports building under macOS Tahoe in particular.
