在項目中導入 pb.go 文件

Question

如何導入生成的pb.go文件，以便調用其中的方法？ 我訪問了 go 的所有示例，它們似乎都是使用github.com/...導入的github.com/...

例子.go

import (
    "github.com/go-chi/chi"
    chiMiddleware "github.com/go-chi/chi/middleware"
    "google.golang.org/grpc"
    "net/http"
    "github.com/easyCZ/grpc-web-hacker-news/server/hackernews"
    hackernews_pb "github.com/easyCZ/grpc-web-hacker-news/server/proto" // Proto directory.
    "google.golang.org/grpc/grpclog"
    "github.com/improbable-eng/grpc-web/go/grpcweb"
    "github.com/go-chi/cors"
    "github.com/easyCZ/grpc-web-hacker-news/server/proxy"
    "github.com/easyCZ/grpc-web-hacker-news/server/middleware"
)

func main() {
    grpcServer := grpc.NewServer()
    hackernewsService := hackernews.NewHackerNewsService(nil)
    hackernews_pb.RegisterHackerNewsServiceServer(grpcServer, hackernewsService)
    ...

目錄結構

main.go

import (
    "bytes"
    "flag"
    "fmt"
    "log"
    "net/http"
    "os"

    "google.golang.org/grpc"
    "google.golang.org/grpc/grpclog"

    "github.com/improbable-eng/grpc-web/go/grpcweb"

    auth "../proto" // Proto directory but doesn't work.
)
...

錯誤

cannot find module for path _/Users/xxx/go/src/athena-server/proto

我嘗試了所有排序絕對和相對路徑以及移動文件，但似乎沒有任何效果。

可以做一個go mod init project ，然后導入位於某個文件夾中的 go 文件，例如文件夾為：

import "project/folder"

我創建了幾個包含這種結構的github 項目，例如 n3dr、bcbsn、go-yq、go-multipart 和 dip。
