I’m using an older version of Trellis (pre 1.0) on a fresh MacOS (latest). When I run vagrant up I’m getting the following error:

`ERROR! Unexpected Exception, this is probably a bug: 'PlaybookCLI' object has no attribute 'options'`

When I uninstall Ansible vagrant up completes without an error, but I’d like to keep Ansible installed. Does anyone have a clue what could be the issue here?

Downgrade ansible to `< 2.8`

```
sudo pip uninstall ansible

sudo pip install ansible==2.7
```

If you followed the install instructions linked [here](https://roots.io/trellis/docs/remote-server-setup/#requirements) and used pip

The downgrade opens up a number of other problems, and personally receive the same error on both Mac and Linux with clean installs of Python 3.7, Ansible 2.7, etc…

Is there another workaround?
