I setup Airflow locally using the Installation and Quickstart pages.

I was able to originally get it up and running, and even follow the Tutorial.

Then when trying my own example which required the following

pip install 'apache-airflow[gcp,google_auth]'

When I try to run webserver with airflow webserver -p 8080 I get the following error:

I was able to get passed this, though not entirely sure of the root cause.

I reinstalled python with brew reinstall python2 and notices there were some conflicts I had to force it to overwrite. Once I got passed this, airflow webserver -p 8080 runs without a problem.

On mac I tried sudo pip install gunicorn and it started working.
