Just for the record, upgrading to Python 3.7 seems to fix it on my machine.

Not sure whether Python 3.6 is supported - the installation page (https://airflow.apache.org/docs/stable/installation.html) at least doesn't mention anything about which Python versions are supported.

That might be some issue with Windows Subsystem for Linux v2 coz Python 3.6 is supported. Not only that Python2.7 is supported too for Airflow <= 1.10.12
