"Not implemented" error when using bunx

Description

I use bunx repomix regularly on my Windows computer, but when trying it on my Mac (Apple Silicon M4 chip), I receive an error:

I was able to pack successfully using a Docker container as a workaround:

docker run -v .:/app -it --rm ghcr.io/yamadashy/repomix

I am using Bun version 1.2.14 (latest at the time of writing).

Sorry if you're not intending to support Bun. I have just gotten used to using it as a replacement and wasn't sure if you'd seen this bug before.

Hi, @lancegoyke
Thank you for the report!

I tried packing Repomix itself with bunx and it seems to work:

bunx repomix

Environment:

bun 1.1.39
Apple M2 Pro
macOS Sonoma 14.4.1

I’ll dig into this further. Since the error is coming from Piscina (the parallel‐processing library), it may be something environment‐specific.

Cheers! Thanks for your acknowledgement. I'm a bit out of my scope here, but let me know if you think I can help test something in the future.
