P3页 少了name变量定义

[ScGPS]

P3 应该把

	switch args[0] {
	case "go":
		goCmd := flag.NewFlagSet("go", flag.ExitOnError)
                goCmd.StringVar(&name, "name", "Go语言", "帮助信息")

改成

	var name string
	switch args[0] {
	case "go":
		goCmd := flag.NewFlagSet("go", flag.ExitOnError)
                goCmd.StringVar(&name, "name", "Go语言", "帮助信息")
