I believe this is the result of missing disablePreGypCopy: true flag in @electron/rebuild options, which was added in #7519 but later removed.
After I patched node_modules/app-builder-lib/out/util/yarn.js the build passes.

Repro: https://github.com/gzdunek/electron-builder-universal - run npm run build
(when running for the first time the actual error is different, re-running it returns an error as above).

@gzdunek can you share the patch you are using?

Also, (hopefully) to temporarily unblock you, you may be able to use electron-builder config option nativeRebuilder: legacy to leverage the previous app-builder-bin go binary for rebuilding native dependencies.

Here is the patch:

Well, we had troubles with that too :)
In our monorepo setup (yarn 1.x) the legacy builder didn't find the native dependency at all (in the debug mode it logs no native dependencies). Because of that, in the universal package, the dependency wasn't rebuilt for x86 arch and the app crashed in the runtime.
This seems to be a regression too, it worked fine in electron-builder@24.13.3.

Thanks for the patch info!

I'm wondering if we should always disablePreGypCopy: true for the electron/rebuild integration. I haven't seen other reports yet for this issue, but current adoption of 25.0.0 is fairly low atm (only 624 downloads as of this moment)

[mmaietta]

Thank you for the test repo. I've opened a PR to resolve this issue since I was also able to reproduce and updated a unit test to cover the universal mac packaging with node-pty. Just updating test snapshots now

[mmaietta]

Please give 25.0.1 a shot and lemme know how it goes! Was no longer able to reproduce with the applied changes

[gzdunek]

25.0.1 solved the issue, thanks!
