Airflow PostgreSQL sqlalchemy

Question

My question: How to install setup Airflow on Python virtual machine?

With

• Airflow 2.8.1
• Postgres 15 and 16
• SQLAlchemy 2.0.27

I get this error:

  File "/home/bigdata/airflow/afvenv/lib/python3.10/site-packages/sqlalchemy/util/langhelpers.py", line 1734, in parse_user_argument_for_enum

    raise exc.ArgumentError(f"Invalid value for '{name}': {arg!r}")

  sqlalchemy.exc.ArgumentError: Invalid value for 'executemany_mode': 'values'
