go - 软件包handlers/gql.go不在GOROOT中(/usr/local/go/src/handlers/gql.go)

Question

我正在尝试导入本地软件包，之前在其他项目中都已经这样做。我不确定如果我做错了什么，或者我在环境中摔坏了，我尝试去1.14 && 1.15。

go mod init github.com/malikiah/go-backend
go run main.go

返回错误:

handlers/gql.go: package handlers/gql.go is not in GOROOT (/usr/local/go/src/handlers/gql.go)

我不确定自己在做什么错。我只希望能够导入本地包。
main.go

package main

import (
    "context"
    "flag"

    //"io"
    "log"
    "net/http"
    "os"
    "os/signal"
    "time"

    //Handlers
    "handlers/gql.go"

    //Middleware
    
    //Services

    //External Packages
    "github.com/gorilla/mux"


)

func main() {

    var wait time.Duration
    flag.DurationVar(&wait, "graceful-timeout", time.Second*15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m")
    flag.Parse()

    port := "3000"
    // Init Router
    router := mux.NewRouter()

    // // route handlers / endpoints
    // graphiqlHandler, err := gql.NewGraphiqlHandler("/api")
    // if err != nil {
    //     panic(err)
    // }

    // router.HandleFunc("/graphql", gqlHandler())
    // router.HandleFunc("/graphiql", graphiqlHandler)
    // router.HandleFunc("/api", errorhandlers.HealthCheckHandler).Methods("GET").Name("HealthCheck")
    // router.HandleFunc("/login", userhandlers.LoginHandler).Methods("POST").Name("Login")
    // router.HandleFunc("/register", userhandlers.RegistrationHandler).Methods("POST").Name("Register")

    // router.NotFoundHandler = http.HandlerFunc(errorhandlers.NotFoundHandler)

    // router.Use(middleware.LoggingMiddleware)

    log.Println("Gopher army ready and is listening on TCP port " + port + "...")
    // Custom server
    srv := &http.Server{
        Addr: "127.0.0.1:" + port,
        // Prevents Slowloris Attacks
        WriteTimeout: time.Second * 15,
        ReadTimeout:  time.Second * 15,
        IdleTimeout:  time.Second * 60,
        Handler:      router, //Passing gorilla mux instance
    }

    go func() {
        if err := srv.ListenAndServe(); err != nil {
            log.Println(err)
        }
    }()

    c := make(chan os.Signal, 1)
    // Acceptes SIGINT for graceful shutdown.

    signal.Notify(c, os.Interrupt)

    // Block until it receives signal.
    <-c

    // Create a deadline to wait for.
    ctx, cancel := context.WithTimeout(context.Background(), wait)
    defer cancel()
    // Doesn't block if no connections, but will otherwise wait until the timeout deadline.
    srv.Shutdown(ctx)

    log.Println("shutting down...")
    os.Exit(0)

}

导入go软件包时，将导入文件夹而不是直接文件。
