docker-compose - Docker Compose 版本错误 - 不工作/开始随机工作

Question

我正在尝试使用 yaml 3.8 版、compose 1.26.2 版、docker-engine 18.09.7 启动 docker-compose。根据 docker 的网站，这应该在 ubuntu 18.04 上一起工作，但我仍然收到以下错误。然后我在写这篇文章的 10 分钟内什么也没做，它又开始工作了？

ERROR: Version in "./docker-compose.yaml" 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.

有以下 docker-compose：docker-compose version

docker-compose version 1.26.2, build eefe0d31
docker-py version: 4.2.2
CPython version: 3.7.7
OpenSSL version: OpenSSL 1.1.0l  10 Sep 2019

具有以下 docker 版本：sudo docker version
