after a fresh install using pip install apache-airflow, any attempts to run airflow end with a python import error:

We have fixed it in Airflow 1.10.9, please install the latest version:

pip install -U apache-airflow

or pin Werkzeug by running pip install werkzeug<1.0

It seemed to be a versioning error, the newer versions of the werkzeug package no longer have the url_encode that airflow is looking for, installing a lower version (pip install werkzeug==0.16.0) resolved the issue and airflow now runs without failing.
