how to Introduce other proto files?

My question: The dependency could not be found in the generated file.

This is my project structure:

./api
├── auth
│   └── service
│       └── v1
│           ├── auth.pb.go
│           └── auth.proto
└── ws
    └── v1
        └── ws.proto

auth.proto:

syntax = "proto3";
package api.auth.service.v1;
import "api/ws/v1/ws.proto";
option go_package = "api/auth/service/v1;v1";

service Auth {
  rpc UserRegister(UserRegisterReq) returns(UserRegisterResp);
}

message CommonResp{
  int32   errCode = 1;
  string  errMsg = 2;
}

message UserRegisterReq {
  api.ws.v1.UserInfo userInfo = 1;
  string operationID = 2;
}

message UserRegisterResp {
  CommonResp CommonResp = 1;
}

ws.proto:

syntax = "proto3";
package api.ws.v1;
option go_package = "api/ws/v1;v1";

message UserInfo{
  string userID = 1;
  string nickname = 2;
  string faceURL = 3;
  int32 gender = 4;
  string phoneNumber = 5;
  uint32 birth = 6;
  string email = 7;
  string ex = 8;
  string createIp = 9;
  uint32 createTime = 10;
  string LastLoginIp =11;
  uint32 LastLoginTime = 12;
  int32  LoginTimes = 13;
  int32 LoginLimit = 14;
  int32 appMangerLevel = 15;
  int32  globalRecvMsgOpt = 16;
  string  invitationCode = 17;
}

go.mod:

module Janna-IM

I executed this command $ protoc --proto_path=. --go_out=. ./api/auth/service/v1/auth.proto at the root of the project.

After executing this command, you will get a new file auth.pb.go, The expected error will occur in this file.

Thank you for your help!

Execute it at the root directory.

$cd Janna-IM

$protoc -I=. --go_out=../../ ws/v1/ws.proto

$protoc -I=. --go_out=. auth/service/v1/auth.proto

auth.proto:

syntax = "proto3";

package pbAuth;
option go_package = "auth/service/v1;pbAuth";

import "ws/v1/ws.proto";

service Auth {
  rpc UserRegister(UserRegisterReq) returns(UserRegisterResp);
}

message CommonResp{
  int32   errCode = 1;
  string  errMsg = 2;
}

message UserRegisterReq {
  server_api_params.UserInfo userInfo = 1;
  string operationID = 2;
}

message UserRegisterResp {
  CommonResp CommonResp = 1;
}

ws.proto:

syntax = "proto3";
package server_api_params;
option go_package = "Janna-IM/api/ws/v1;server_api_params";

message UserInfo{
  string userID = 1;
  string nickname = 2;
}

How import is written depends on where in terminal the protoc command.
