Airflow 2 - ImportError: cannot import name 'BashOperator' from 'airflow.operators'

After upgrading to Airflow 2, I got that error in some DAGs:

ImportError: cannot import name 'BashOperator' from 'airflow.operators'

I resolved by change the import.

• old one (https://github.com/apache/airflow/blob/v1-10-stable/airflow/hooks/base_hook.py)

from airflow.operators import BashOperator

• the new one that works (https://github.com/apache/airflow/blob/v2-0-stable/airflow/hooks/base.py)

from airflow.hooks import BashOperator
