To install this tap, simply run brew install aodj/ansible/ansible
When installing this tap, problems may arise as time passes, wherein the Homebrew bottle that the installation process relies upon is removed from the https://homebrew.bintray.com repository (this is the case as of Sept 2018).
In this event, the installation process will attempt to install the dependencies listed in ansible.rb which may present issues when running against macOS; as an example, lxml is notoriously painful to install. If this happens, simply install lxml manually (ie: pip install lxml) and then after tapping this formula (brew tap aodj/ansible) comment out the lxml resource in the formula.
