Yup, I wrote about it yesterday, but the issue was closed #7689 (comment)

Also, if you try to change the create admin call in docker-init.sh:

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 to compose on branch 0.30)

Downloaded the package a couple of minutes ago, same issue after completing the admin user credentials prompts

Was unable to import superset Error: No module named 'flask_talisman'

I have the same problem

Error: Failed to find Flask application or factory in module "app". Use "FLASK_APP=app:name to specify one.

Hi,

This works: sudo docker-compose run -e FLASK_APP=superset:app --rm superset ./docker-init.sh

I'll submit a PR to solve it or on docker-init.sh or on README.md

I had the exact same problem with the new version. Did you manage to fix it? Thank you!

I still have an issue with Was unable to import superset Error: No module named 'flask_talisman' and sudo docker-compose run -e FLASK_APP=superset:app --rm superset ./docker-init.sh doesn't help
