2. pb文件引用情况

• pb文件(api.pb.go)

`

// Code generated by protoc-gen-go. DO NOT EDIT.
// versions:
// protoc-gen-go v1.36.10
// protoc v5.28.0--rc3
// source: client_api.proto

package client_api

import (
protoreflect "google.golang.org/protobuf/reflect/protoreflect"
protoimpl "google.golang.org/protobuf/runtime/protoimpl"
reflect "reflect"
sync "sync"
unsafe "unsafe"
)

const (
// Verify that this generated code is sufficiently up-to-date.
_ = protoimpl.EnforceVersion(20 - protoimpl.MinVersion)
// Verify that runtime/protoimpl is sufficiently up-to-date.
_ = protoimpl.EnforceVersion(protoimpl.MaxVersion - 20)
)
`

• 引用模块文件(handle.go)

`

package handler

import (
"context"
pb "games/api"
"games/app/mail/internal/service"

"github.com/gogo/protobuf/proto"
"github.com/redis/go-redis/v9"

)
`

3. 报错原因

解析pb文件库和生成库不一致

• 生成库: "google.golang.org/protobuf/runtime/protoimpl"

• 解析库: "github.com/gogo/protobuf/proto"

4. 解决

解析库替换为: "google.golang.org/protobuf/proto"
