I'm trying to install airflow 2.6 following the quick start guide here.

Installation appears to work fine following the guide above.

But when I get to the setup part, specifically the airflow standalone or airflow db init commands, I get the following error:

File "/usr/local/anaconda3/envs/airflow_3_7_2023/lib/python3.7/site-packages/alembic/operations/batch.py", line 700, in drop_constraint
    raise ValueError("No such constraint: '%s'" % const.name)
ValueError: No such constraint: 'dag_tag__fkey'

Seems to be something with the alembic package?. The airflow installation also installed alembic. Should I uninstall alembic and try different versions?

I've tried airflow install and setup in python 3.7 and 3.8 envs and gotten the same error in each. I'm on mac Ventura 13.2.1

Any ideas are appreciated, thanks in advance!

For me helped restarting the airflow db

airflow db reset

After that you can init your db by

airflow db init

Hope it will helps
