skia-renderer feature fails to build on aarch64-apple-darwin

[otiv-wannes-vanleemput]

It seems the build script tries to download binaries which do not exist:

https://github.com/rust-skia/skia-binaries/releases/download/0.78.2/skia-binaries-ec00cf219c4901d785ed-aarch64-apple-darwin-gl-metal-textlayout.tar.gz

Full output:

  The variable "skia_use_freetype_woff2" was set as a build argument
  but never appeared in a declare_args() block in any buildfile.

  To view all possible args, run "gn args --list <out_dir>"

  The build continued as if that argument was unspecified.

  Done. Made 83 targets from 45 files in 198ms

Should I post this here or in the skia repository? Got a bit confused by the "custom build command" part

[tronical]

It's okay that the download fails, it's okay (and intentional here) that the build falls back to building Skia from source.

ModuleNotFoundError: No module named 'pipes'

This is the real error here. I was also reported upstream at rust-skia/rust-skia#1049 .

Most likely this is caused by the use of Python 3.13 from home-brew on your system. I suggest to see if you can work around it by either switching to Python 3.12 from home-brew or not using Python from home-brew altogether - it builds with /usr/bin/python3 as shipped by macOS itself.

[otiv-wannes-vanleemput]

Switching to /usr/bin/python3 indeed solved this issue for me, many thanks!
