grpc-tools package does not work with M3 Pro Mac

[Lukas-Kullmann]

Problem description

When I install grpc-tools and try to run code generation (i.e. node node_modules/.bin/grpc_tools_node_protoc [...]), I get an error

node_modules/.bin/grpc_tools_node_protoc [...]
node:internal/child_process:414
    throw errnoException(err, 'spawn');
    ^

Error: spawn Unknown system error -86

    at node:internal/main/run_main_module:23:47 {
  errno: -86,
  code: 'Unknown system error -86',
  syscall: 'spawn'
}

Node.js v18.18.2

I then tried to run the command that the protoc.js file generates directly

node_modules/grpc-tools/bin/protoc --plugin=protoc-gen-grpc=node_modules/grpc-tools/bin/grpc_node_plugin [...]

But that gives me a different error

zsh: bad CPU type in executable: node_modules/grpc-tools/bin/protoc

Reproduction steps

See above.

• install grpc-tools
• run node_modules/grpc-tools/bin/protoc --version
• (you get the same error when running node_modules/grpc-tools/bin/grpc_node_plugin --version)

Environment

• OS name, version and architecture: MacOS 14.2.1 arm64 (uname -a prints Darwin [device id] 23.2.0 Darwin Kernel Version 23.2.0: Wed Nov 15 21:54:51 PST 2023; root:xnu-10002.61.3~2/RELEASE_ARM64_T6030 arm64)
• Node version 18.18.2 (also tried 18.19.0)
• Node installation method volta
• Package name and version grpc-tools@1.12.4

Additional context

I don't think this library is responsible for building the binary that is not working for me, but I also don't know where else to report this error to.

@Lukas-Kullmann any updates ?

[Lukas-Kullmann]

I installed rosetta (softwareupdate --install-rosetta via CLI) and now it works. Don't know why I need it though.
