Verification

• My "brew doctor output" says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

Just run ansible, or ansible-playbook

What happened (include all command output)?

 ~ ansible
ERROR: No module named 'markupsafe'
 ~ ansible-playbook
ERROR: No module named 'markupsafe'

What did you expect to happen?

I would expect ansible to not fail :)

Step-by-step reproduction instructions (by running brew commands)

it happened following the upgrade `ansible 8.6.0 -> 8.6.0_1`, with the regular `brew upgrade`, on latest MacOS, on a M2 Mac.
I could also reproduce the problem on another Mac, with the same specs.

Probably Homebrew/brew#16152

This seems to be related to the Python 3.12 upgrade in formula... see commit history for formula: https://github.com/Homebrew/homebrew-core/commits/2c2b8c195ea0d28ff1ff43215308bd0563b94564/Formula/a/ansible.rb

Unfortunately all related dependencies (i.e. packages like python-markupsafe) were before that installed with in my case Homebrew Python 3.11.6

Solution for me was:

brew remove ansible python-markupsafe #and probably some other related dependencies
brew install ansible # which then installed all the appropriate dependencies within the new Python scope

Fixed for me by first uninstalling markupsafe and ansible and then installing ansible back (which pulls markupsafe)

brew uninstall python-markupsafe ansible && brew install ansible

Thanks @todeveni , I can now run ansible again.

There are 2 places that can cause issue for users:

1. homebrew-core issue - There was no revision bump to python-markupsafe so users did not get update with python@3.12 support - should hopefully be fixed with python-tabulate: revision bump for python@3.12 support #154145 python-markupsafe: revision bump for python@3.12 support #154196
2. brew issue - Some installs/upgrades didn't automatically upgrade revision bumps. Should already be fixed now that Store and use revision in tab runtime dependencies brew#16152 is merged and in brew release.
