在docker-compose出现了问题

此处镜像已经404

这应该不是404，是网络的问题，重新试一试就好了。

请问这是什么原因呢？ ERROR: Version in "./single.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the services key, or omit the version key and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
