tzlocal version conflict error

[AXington]

Hi,

We just tried installing your plugin on our docker image, which is based on the nearly ubiquitous puckel docker image for airflow, and we're now getting the error following this description about a tzlocal version conflict. It's odd because I don't see where there's a requirement for tzlocal<2.0.0,>=1.4
anywhere in your code. Our application has a requirement of >= 2.0.0. So I'm a bit confused as to why we're seeing that when installing your plugin.

Airflow version: 1.10.6
base container: python:3.7.5-slim-buster
using the KubernetesExecutor with PythonOperator
airflow installed with these options/plugins: apache-airflow[crypto,postgres,hive,jdbc,kubernetes,statsd,ssh]

I am not entirely sure why you have a tzlocal conflict. I don't think it is due to the airflow exporter. Maybe try to get into the docker container and do pip show tzlocal to see why this particular version is being installed?
