Errors with building the wheel while installing

[M0tix]

Hello everyone. I apologize in advance if this issue might be a bit stupid. I am not much of a developer, and I dont know a lot about python. Im on Debian GNU/Linux 12 (bookworm) i686, my CPU is a Intel i7 M 620 (4) @ 2.667GHz. When I try to install skia-pathops, I get the following error log:

pip3 install --upgrade skia-pathops --break-system-packages
Defaulting to user installation because normal site-packages is not writeable

looks like the https://github.com/fonttools/skia-builder that we use to build the libskia does not support 32-bit Linux (i686). I'm afraid I don't know how to help with this.

Is there a reason you can't use the 64-bit version of Python, for which we do already publish pre-compiled wheels?
