How to import cue.mod in .go file

[ningan123]

I wanna import cue.mod in mian.go file, but got error:

# go run main.go
package "mod.test/pkg:bar" imported but not defined in :
    3:8

scheme: 
_|_ // package "mod.test/pkg:bar" imported but not defined in  (and 1 more errors)

How to fix it?

main.go

package main

import (
	"errors"
	"fmt"
	"os"
	"path/filepath"

	"cuelang.org/go/cue"
	"cuelang.org/go/cue/cuecontext"
	cueerror "cuelang.org/go/cue/errors"
	// "cuelang.org/go/mod/module"
)

func main() {

	ctx := cuecontext.New()

	clusterVal := ctx.NewList()

	confPath := "xxx"
	fileData, err := os.ReadFile(filepath.Join(confPath, "in.cue"))
	if err != nil {
		fmt.Println(err.Error())
	}

	// fmt.Println(module.Version.Path())
	scheme := ctx.CompileBytes(fileData, cue.Scope(clusterVal))
	if scheme.Err() != nil {
		msg := cueerror.Details(scheme.Err(), nil)
		fmt.Println(errors.New(msg))
	}
	fmt.Printf("scheme: \n%s\n", scheme)
}
