docker-compose沒有看到docker

Question

如果您自己啟動docker-run，則可以正常運行；如果使用docker-compose來運行，則無法正常運行

roman@debian ~/D/O/devops> docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Digest: sha256:083de497cff944f969d8499ab94f07134c50bcf5e6b9559b27182d3fa80ce3f7
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

好的，已經解決了，以前是從存儲庫安裝compose，現在是通過pip安裝的，並且可以正常工作
