[Other]: gen.cmd failed

[zhaolibo1989]

What would you like to share?

I use gen.cmd to generate *.go, but get errors as follow:

D:\work\code\OpenIMSDK\protocol>protoc --go_out=plugins=grpc:./conversation --go_opt=module=github.com/OpenIMSDK/protocol/conversation conversation/conversation.proto
--go_out: protoc-gen-go: plugins are not supported; use 'protoc --go-grpc_out=...' to generate gRPC

See https://grpc.io/docs/languages/go/quickstart/#regenerate-grpc-code for more information.

D:\work\code\OpenIMSDK\protocol>protoc --version
libprotoc 22.0

D:\work\code\OpenIMSDK\protocol>protoc-gen-go --version
protoc-gen-go v1.29.1

D:\work\code\OpenIMSDK\protocol>protoc-gen-go-grpc --version
protoc-gen-go-grpc 1.3.0

D:\work\code\OpenIMSDK\protocol>

Additional information

I use 'protoc --go-grpc_out=...' to generate gRPC, and then, failed again.

D:\work\code\OpenIMSDK\protocol>protoc --go-grpc_out=plugins=grpc:./conversation --go_opt=module=github.com/OpenIMSDK/protocol/conversation conversation/conversation.proto
Unknown flag: --go_opt

使用go install github.com/golang/protobuf/protoc-gen-go后，protoc-gen-go不能单独查看版本号。

C:\Users\Administrator>protoc-gen-go --version
protoc-gen-go: unknown argument "--version" (this program should be run by protoc, not directly)

生成的 *.go 中提示的 protoc-gen-go 版本有变化。

// Code generated by protoc-gen-go. DO NOT EDIT.
// versions:
//  protoc-gen-go v1.31.0 ****这里原来是 v1.29.1
//  protoc        v4.22.0
// source: conversation/conversation.proto

试图 go install 指定 v1.29.1 版本号安装时，提示没有这个版本。如何控制这个版本，原文件的 v1.29.1 版本是哪里来的？

C:\Users\Administrator>go install github.com/golang/protobuf/protoc-gen-go@v1.29.1
go: github.com/golang/protobuf/protoc-gen-go@v1.29.1: github.com/golang/protobuf/protoc-gen-go@v1.29.1: invalid version: unknown revision protoc-gen-go/v1.29.1

使用 v1.31.0 版本的 protoc-gen-go 生成的 go 文件对 protocol 的使用有什么影响？

got it

I have also encountered this problem.

I solve to use go install github.com/golang/protobuf/protoc-gen-go@latest. It work it.

So anyone have this problem. You can refer to the article mentioned in the previous comment.

you can find version in here. also everyone package you can find in pkg.go.dev.

So I have to answer the question. First, update protoc-gen-go usually is not breaking change. It is not problem. Just use proto file generate corresponding go file. So you worry the version.
