title: BashOperator not found on Airflow install on Raspberry Pi
body: <p>I'm not sure how to approach this issue -- other posts to do with <code>ModuleNotFoundError</code> are solved by reinstalling the relevant package, however it's clear that this is not the issue because the example bash operator DAG runs. So is my issue to do with how Airflow was installed? At this point I'm looking at reinstalling Airflow via the <a href="https://github.com/puckel/docker-airflow" rel="nofollow noreferrer">puckel Docker container</a>.</p>
