Subject: [PATCH] maybe version not update

hochan@hochan-node:~/Desktop/pfc/dockercompose$ sudo docker-compose up --build
ERROR: Version in "./docker-compose.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.
