This typically happens if you have 2 rust installations (the built from a source tarball note seconds this since this shouldn't show for rustup instances) with rustup not being the primary one. If that's the case, either remove the other installation or try adding the correct target to that other rust instance too.

ok, thanks for you answer. I uninstall rust : rustup self uninstall (note i am a beginer on rust) and run again npm run tauri build -- --target universal-apple-darwin

Same result ...

[FabianLars]

well, you're still missing the target for this rust installation but i don't know how to add it, especially since i don't even know where it comes from, homebrew? Either way, i'd recommend getting rid of that too and only using the rustup installation...
