Run demo failed!

test.proto

 syntax = "proto3";
 package your.service.v1;
 option go_package = "github.com/yourorg/yourprotos/gen/go/your/service/v1";
 import "google/api/annotations.proto";
 message StringMessage {
   string value = 1;
 }

 service YourService {
   rpc Echo(StringMessage) returns (StringMessage) {
    option (google.api.http) = {
        post: "/v1/example/echo"
        body: "*"
    };
   }
 }

When I run 【protoc -I . --grpc-gateway_out ./gen/go --grpc-gateway_opt logtostderr=true --grpc-gateway_opt paths=sourc
e_relative test.proto】, it is the same as the command in demo.

I failed and got an error message

Hm, that should work, but this isn't really the right place for this sort of debugging, could you join our Slack channel (#grpc-gateway) on Gophers slack and I can help figure out what the problem is?

Closing as this is an environment issue.
