2. pb文件引用情况

• pb文件(api.pb.go)

// versions:
//  protoc-gen-go v1.36.10
//  protoc        v5.28.0--rc3
// source: client_api.proto

package 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)

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"

5. 版本查看

• protoc --version

libprotoc 28.0-rc3

• go list -m google.golang.org/protobuf

google.golang.org/protobuf v1.36.7
