Error: no such option: --app

When i followed the documentation https://superset.incubator.apache.org/installation.html to install the superset (Cloud-native! - Start with Docker) in the third step docker-compose run --rm superset ./docker-init.sh i am getting an error WARNING: Image for service superset was built because it did not already exist. To rebuild this image you must use docker-compose build or docker-compose up --build.

• ‘[’ 1 -ne 0 ‘]’
• exec ./docker-init.sh
• flask fab create-admin --app superset Error: no such option: --app

I tried with multiple machines and the result was same. I cannot continue further due to this error.

under the dir incubator-superset/contrib/docker, follow these:

1. add this line - ./docker-init.sh:/home/superset/docker-init.sh to docker-compose.yml
2. change lask fab create-admin --app superset to fabmanager create-admin --app superset in ./docker-init.sh
3. run docker-compose run --rm superset ./docker-init.sh again

I’ve tried with fabmanager create-admin --app superset and I got this error: "There is no appbuilder var on your package, you can use appbuilder parameter to config"

(I got also this same error if I try on branch 0.30)
