Trellis no longer supports Ansible 2.3.1.0

[fullyint]

With pip it takes a few seconds to change to whichever version of Ansible you need for a given project.

For this current project for which you’ve updated Trellis, you could
pip install ansible==2.4.0.0
If running 2.4 doesn’t work for this project (e.g., in case you have customizations that are incompatible with 2.4), hopefully you have this project under version control and can save your latest updates to a separate branch then undo changes.

When you need to work on a project with an older version of Trellis that doesn’t accommodate Ansible 2.4 (i.e., produces errors like these), you could
pip install ansible==2.3.2.0

Using pip for changing Ansible version has always been quick and reliable for me, but note the discussion of using Virtualenv to address the issue:

Updated to Ansible 2.4, deploys broken, now what?

I just ran into this myself and wanted to post back to emphasize that Virtualenv really is handy for this sort of thing. The gist of it is: Install Virtualenv- sudo pip install virtualenv Create a directory, anywhere, call it whatever you want. I called mine “virtualenvs”. I made mine in my home directory, and made it a hidden directory. mkdir ~/.virtualenvs && cd ~/.virtualenvs If I want to create an environment to run Ansible 24.0.0 I could run (from my .virtualenv directory) virtualenv ans…
