前言

在 proto 文件夹下执行如下命令：

$ protoc --go_out=plugins=grpc:. *.proto

报错：无法确定Go导入路径

protoc-gen-go: unable to determine Go import path for "search.proto"

Please specify either:
        ? a "go_package" option in the .proto source file, or
        ? a "M" argument on the command line.

See https://developers.google.com/protocol-buffers/docs/reference/go-generated#package for more informa
tion.

--go_out: protoc-gen-go: Plugin failed with status code 1.

解决方法

在所有的 .proto 文件中指定路径

option go_package ="./pb";

举例：proto文件 新增第三句代码

syntax = "proto3";

package proto;

option go_package ="./proto"; // 指定RPC文件生成路径地址

service SearchService {
    rpc Search(SearchRequest) returns (SearchResponse) {}
}

message SearchRequest {
    string request = 1;
}

message SearchResponse {
    string response = 1;
}
