文中的demo会报错

func main() {
client := redis.NewClient(&redis.Options{
Network: "tcp",
Addr: "127.0.0.1:6379",
DB: 0,
})

rc := rockscache.NewClient(client, rockscache.NewDefaultOptions())
v, err := rc.Fetch("key2", 400, func() (string, error) {
	return "value2", nil
})
if err != nil {
	fmt.Println(err)
	return
}
fmt.Println(v)

}
key2的值为"aaa"，获取时报下面的错误
ERR Error running script (call to f_a307994a908d94d53a2b772ddc6cf08109e0a828): @user_script:2: WRONGTYPE Operation against a key holding the wrong kind of value

key2的值，或者为空，或者为hash，而不是string。你可以删掉key2，重新运行一下
