Ansible Install on OS X

I started out trying to use Ansible via Home Brew, but I needed to add a pip library (docker-py) and read that even Brew’s ansible uses the systems python. So I removed python and ansible completely from brew.

I then tried to install Ansible via the system pip. Now I get ‘bad interpreter’ errors:

Any tips to either rescue my system install or make Brew’s Ansible use Brew’s pip library would be greatly appreciated.

/bin/ansible- uses “/usr/bin/env” to launch whatever python is in your path, which is pretty standard practice.

It seems like you might have /usr/bin/python symlinked to something that is a broken symlink or is not marked executable.

pip install on OS X is a fine way to do things.

We don’t recommend homebrew because they have applied patches not in the main ansible tree, and have not contributed them back upstream, which makes it confusing when people report having installed from brew.

Another super easy way to run from OS X is to just do a checkout and:

source ./hacking/env-setup

Ansible runs very easy from source once deps are available.
