I am trying to start my airflow webserver, but it says it is an unrecognised argument
$ airflow webserver

airflow: error: unrecognized arguments: webserver
Seeing as most of the other arguments are broken too, I have already tried to reinstall airflow:
sudo pip install --upgrade --force-reinstall airflow==1.7.1.3
It was working just fine until I decided to restart it...
回答1:
I figured it out as I was writing the last line of the question. I was restarting because I updated a DAG, in which, I had added an ArgumentParser
parser = argparse.ArgumentParser()
parser.add_argument(
'-v', '--verbose',
help="Print lots of debugging statements",
action="store_const", dest="loglevel", const=logging.DEBUG,
default=logging.INFO,
)
Apparently that is not allowed in Airflow DAGs
