生成网关原型-grpc网关时的proto grror :程序未找到或不可执行

Question

我也找到了类似的职位，但它们已经相当老了，很遗憾，它们并没有解决我的问题。

我正在尝试为我的GoLang GRPC服务添加一个网关

PROJ_PATH=${CURDIR}

.PHONY: proto
proto: ## Generate protobuf code
# Compile proto files inside the project.
    protoc api.proto --proto_path=${PROJ_PATH}/proto --go_out=. --go-grpc_out=. \
            --grpc-gateway_out . \
            --grpc-gateway_opt generate_unbound_methods=true \
            --openapiv2_out . \
            --openapiv2_opt logtostderr=true \
            --openapiv2_opt generate_unbound_methods=true

我添加了这两个依赖项

go get github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway
go get github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2

但我还是明白他的错误

protoc-gen-grpc-gateway: 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-gateway_out: protoc-gen-grpc-gateway: Plugin failed with status code 1.
make: *** [proto] Error 1

我不得不删除GRPC文件中的导入和网关选项，因为这个错误，所以看起来我有错误的插件，但是读这里告诉我并非如此。

google/api/annotations.proto: File not found.
api.proto:5:1: Import "google/api/annotations.proto" was not found or had errors.
make: *** [proto] Error 1

syntax = "proto3";

option go_package = "pkg/api";

import "google/api/annotations.proto";  <---- had to remove

service ApiService {
    rpc Test(TestRequest) returns (TestResponse){

        option (google.api.http) = {  <---- had to remove
            get: "/v1/test"
            body: "*"
        };
    }
}

如有任何建议，将不胜感激。

-解决了

go install \
    github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway@latest \
    github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2@latest

然后将路径添加到proto命令中。

--plugin=protoc-gen-grpc-gateway=${GOPATH}/bin/protoc-gen-grpc-gateway \

完全命令..。

protoc api.proto --proto_path=${PROJ_PATH}/proto --go_out=. --go-grpc_out=. \
       --grpc-gateway_out . \
       --grpc-gateway_opt generate_unbound_methods=true \
       --plugin=protoc-gen-grpc-gateway=${GOPATH}/bin/protoc-gen-grpc-gateway \
       --openapiv2_out . \
       --openapiv2_opt logtostderr=true \
       --openapiv2_opt generate_unbound_methods=true

我不得不像这样安装二进制文件

go install \
    github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway@latest \
    github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2@latest

然后用路径更新proto命令。

--plugin=protoc-gen-grpc-gateway=${GOPATH}/bin/protoc-gen-grpc-gateway \

完全原命令

PROJ_PATH=${CURDIR}

.PHONY: proto
proto: ## Generate protobuf code
# Compile proto files inside the project.
    protoc api.proto --proto_path=${PROJ_PATH}/proto --go_out=. --go-grpc_out=. \
           --grpc-gateway_out . \
           --grpc-gateway_opt generate_unbound_methods=true \
           --plugin=protoc-gen-grpc-gateway=${GOPATH}/bin/protoc-gen-grpc-gateway \
           --openapiv2_out . \
           --openapiv2_opt logtostderr=true \
           --openapiv2_opt generate_unbound_methods=true
