Error FileNotFoundError while using Airflow docker compose

I was trying to use docker-compose to up the Airflow, I have used it in a directory where I have `docker-compose.yaml.
I have not changed docker-compose.yaml and just used the standard one from Apache Airflow. Just to say, I have installed Docker before and used it.
Here is the output in the console:

(base) ruslanpilipyuk@MacBook-Pro-Ruslan airflow-local % docker-compose -f docker-compose.yaml up -d

    It seems like airflow user definition missing.

    Try to run the following (one time) and then run the docker-compose

    echo -e "AIRFLOW_UID=$(id -u)" > .env

    I got same exact error when attempting ‘docker-compose up’ on my Redhat 7.9 VM.
    Our Unix admin was helping me undo a recent server patch which I thought might be causing issues. He asked to run ‘docker version’. I did. It spewed results. Last line read:
    ==> "Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"
    Doh! He then started docker daemon as root with ‘systemctl start docker’.
    I ran ‘docker-compose up’ again.
    Docker’s up and running.

    If you have Docker Desktop installed on your local machine, just start/open it. Then try to run the docker command and it will execute successfully.
