undefined问题

[homeeecode3]

按照文档的方式写了示例代码： package main

import ( "bytes" "fmt" "io/ioutil" "log"

"github.com/chai2010/webp"

)

func main() { var buf bytes.Buffer var width, height int var data []byte var err error

// Load file data
if data, err = ioutil.ReadFile("./testdata/1_webp_ll.webp"); err != nil {
    log.Println(err)
}

// GetInfo
if width, height, _, err = webp.GetInfo(data); err != nil {
    log.Println(err)
}
fmt.Printf("width = %d, height = %d\n", width, height)

// GetMetadata
if metadata, err := webp.GetMetadata(data, "ICCP"); err != nil {
    fmt.Printf("Metadata: err = %v\n", err)
} else {
    fmt.Printf("Metadata: %s\n", string(metadata))
}

// Decode webp
m, err := webp.Decode(bytes.NewReader(data))
if err != nil {
    log.Println(err)
}

// Encode lossless webp
if err = webp.Encode(&buf, m, &webp.Options{Lossless: true}); err != nil {
    log.Println(err)
}
if err = ioutil.WriteFile("output.webp", buf.Bytes(), 0666); err != nil {
    log.Println(err)
}

fmt.Println("Save output.webp ok")

}

go.mod中： module test_prj

go 1.20

require ( github.com/chai2010/webp v1.1.1 )

go run 的时候报错：
