What version of the CLI are you using?

[zackbrown]

I can reproduce this on 0.10.7:

1. cargo install pax-cli --force
2. pax-cli new xcodetest
3. cd xcodetest && pax-cli run --target=macos. The same error message is presented.

Thanks for the report @Vjze ; we've filed this bug in our tracker and will update this issue when we resolve it.

For whoever takes this on, it looks like the published version of the CLI (as opposed to the monorepo libdev version) is failing to unpack pax-swift-cartridge. Either it isn't getting bundled with the binary, or perhaps our recursive unpacking logic is failing (possibly not handling a symlink/etc. correctly — and we do have symlinks in pax-swift-cartridge.)

Notice the missing pax-swift-cartridge below; this is in xcodetest/.pax/pkg/pax-chassis-common after getting the error above:
