sql-training环境搭建

[jacky-cui]

hi，   想在本地搭建flink-sql-training 学学flink sql，但是新建文件夹，下载docker-compose.yml，然后进入到docker-compose.yml所在文件夹，然后执行docker-compose up -d 的时候，报错如下：ERROR: build path /root/flink-sql-training/images/flink-image either does not exist, is not accessible, or is not a valid URL. 请问这种问题如何解决
