怎么在go的子路吗下面引用子包下面的函数

我引用子包出现了 build command-line-arguments: cannot load blog/controller/home: malformed module path "blog/controller/home": missing dot in first path element

相关代码

• 目录结构

src
    blog
        controller
            home
                IndexController.go
        main.go    

• 下面是我的main包里面的代码

package main

import (
    "blog/controller/home"  // 这里在goland编辑器编译的时候提升错了
    "github.com/kataras/iris"
    "github.com/kataras/iris/middleware/logger"
    "github.com/kataras/iris/middleware/recover"
    "log"
)

func main() {
    app := iris.New()
    app.Logger().SetLevel("debug")
    app.Use(recover.New())
    app.Use(logger.New())

    app.Get("/", home.Index)

    log.Fatal(app.Run(iris.Addr(":8089")))
}

• go.mod

module blog

我的go环境都在同一个目录环境下，为什么还报这个错误呢，我的go版本是 go version go1.13.1 darwin/amd64

提示的错误信息是

go: finding github.com/Shopify/goreferrer latest
go: finding github.com/eknkc/amber latest
go: finding github.com/flosch/pongo2 latest
go: finding github.com/kataras/golog latest

build command-line-arguments: cannot load blog/controller/home: malformed module path "blog/controller/home": missing dot in first path element

请问各位大佬们我哪里写错了呀
