Command --grpc-swift_out=. not work

[gulivero1773]

I use protoc -I=Sources/Protos --swift_out=Sources/App/Generated --grpc-swift_out=Sources/App/Generated Sources/Protos/example.proto but I have error - protoc-gen-grpc-swift: program not found or is not executable Please specify a program using absolute path or make sure the program is available in your PATH system variable --grpc-swift_out: protoc-gen-grpc-swift: Plugin failed with status code 1
And it problem with --grpc-swift_out= but I use tutorial, what I do wrong?

Hey @gulivero1773 - I believe the issue here is that you're invoking protoc directly, and you haven't specified a path to the Swift plugin that understands how to generate Swift code from the proto.

You will need to build it from source from the grpc-swift package: swift build --product protoc-gen-grpc-swift

You can then add the resulting binary to your PATH or use the option --plugin=protoc-gen-grpc-swift=<path to plugin> to point to the plugin.

You know where PATH to plugin proto? I use Xcode and build in Xcode

I instal protoc-gen-grpc-swift, but console show for me - error: no product named 'protoc-gen-grpc-swift'

I'm having the same issue. I brougt this up here on the swift-protobuf issues board, but here's what I'm encountering:

With the latest version of protoc-gen-grpc-swift using the grpc options with protoc such as:

--grpc-swift_opt
--grpc-swift_out
--grpc-swift_opt

Results in this error:

protos/studio/studio.proto:13:1: warning: Import protos/grid/grid.proto is unused.
protos/test/test2.proto:5:1: warning: Import protos/shared/location.proto is unused.
protoc-gen-grpc-swift: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--grpc-swift_out: protoc-gen-grpc-swift: Plugin failed with status code 1.

The location of protoc-gen-grpc-swift is in my path. I've confirmed this. However since the binary renamed to protoc-gen-grpc-swift-2 I think this might be causing some issues.

Specifying the location of protoc-gen-grpc-swift-2 by using the --plugin option results in the same error.

When renaming the symlink from protoc-gen-grpc-swift-2 to protoc-gen-grpc-swift in /opt/homebrew/bin, it ran, however it fails to compile, resulting in this error:

The only way we've been able to get around this is by compiling grpc-swift version 1.26.1 and swift-protobuf 1.29.0 and use those.

When renaming the symlink from protoc-gen-grpc-swift-2 to protoc-gen-grpc-swift in /opt/homebrew/bin, it ran, however it fails to compile, resulting in this error:

You're using the plugin for v2 (protoc-gen-grpc-swift-2) which won't work with the runtime for v1.

This project doesn't support, maintain or update the homebrew plugin, so you need to build it from source. If you're depending on grpc-swift you can do this from your package by running swift build --product protoc-gen-grpc-swift.
