STEPS TO REPRODUCE

Just install ansible and ansible-lint using pacman

Desired Behavior

Ansible lint prints correct version

Actual Behavior

The exception is thrown, see tracebback above

pacman is not a supported installation method, so I will have to close this bug as won't fix. Still, we would likely accept a PR that makes it easier to build a pacman package if proposed.

@ssbarnea I found out that this is caused by missing python-setuptools package. I think it's a problem of arch distribution because this package must depends on python-setuptools
