Issue in sudo docker-compose -f setup.yml up

[guruprasanthexzatech]

I ran the following command sudo docker-compose -f setup.yml up after pulling request from github.
Then i got the error
ERROR: Version in "./setup.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") 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/

Then in setup.yml and docker-compose.yml i changed the version to 3.3 and then ran the command and then i got the following error.
WARNING: The PWD variable is not set. Defaulting to a blank string.
