ERROR! need more than 2 values to unpack while using ansible commands

[brya...@santecapital.com]

Upgraded to Ansible 2.0.0.2 via brew and can't run any of the core ansible commands on OSX.

> ansible localhost -m ping -vvvv

Using /Users/bryanyu/Projects/data-repo/ansible/ansible.cfg as config file

ERROR! need more than 2 values to unpack

I am not using any spaces in my group names. (#13917) and my ansible.cfg file is standard. Here is my inventory file:

> cat inventory/base

[localhost]

127.0.0.1

# Empty tags for aliases

[tag_Name_hermes_loader]

[tag_Name_test_loader]

# Groups populated by aliases

[dataloader:children]

tag_Name_hermes_loader

[testloader:children]

tag_Name_test_loader

Any help?
