Ansible not recognizing deb parameter for aptitude

Question

According to http://docs.ansible.com/apt_module.html, the aptitude module allows installation from a .deb file:

# Install a .deb package
- apt: deb=/tmp/mypackage.deb

But running Ansible 1.9.2 or 1.8.4 on Ubuntu 14.04, this config:

- name: install riak
  apt: deb=/data/riak/riak.deb update_cache=no

produces this output:

TASK: [riak | install riak] *************************************************** 
failed: [riak-server-1] => {"failed": true}
msg: unsupported parameter for module: deb

The same Ansible script works fine on Macs running Ansible 1.8.4 and 1.9.

The guest in all cases is a Vagrant-created ubuntu/trusty64. The entire VM creation and setup is done with Vagrant and Ansible, and we're all running with the same Vagrant/Ansible files.

Edit:

>ansible-playbook --version
 ansible-playbook 1.9.2
   configured module search path = /usr/share/ansible

>ansible --version

It's built from source:

It really looks to me like it's picking up an old version of apt.py from somewhere. I ran sudo find / -name apt.py, and there are several copies in my home, but only the one under /usr.

Edit:

I removed all the apt.py instances laying around, so that:

Answer 1

Well, it's now working. It turns out that there was a remnant of ansible left over from running sudo apt-get install ansible some time ago. So, even though I had tried to completely scrub any ansible bits left using

sudo rm -rf /usr/local/lib/python2.7/dist-packages/ansible* /usr/local/bin/ansible* /usr/bin/ansible*

and even though there was no old apt.py left anywhere on my system, sudo apt-get remove ansible found something to remove. I thought I had already run that before ever going down the source route, but apparently not.

>sudo apt-get remove ansible

The following packages were automatically installed and are no longer required:

Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:

After this operation, 2,758 kB disk space will be freed.

After that, I re-cloned the source:

git clone git@github.com:ansible/ansible --recursive

and rebuilt:

sudo make clean install
sudo /bin/bash ./hacking/env-setup

Now the install from a .deb file works:
