SUMMARY

Including ansible_python_interpreter='/usr/bin/env python' in inventory leads to module failure (OSError: [Errno 2] No such file or directory). Setting ansible_python_interpreter to specific path (e.g. /usr/local/bin/python) resolves issue.

STEPS TO REPRODUCE

Create inventory file:

[local]
127.0.0.1 ansible_connection=local ansible_python_interpreter='/usr/bin/env python'

Create playbook:


---
- hosts: all
  tasks:
    - shell: echo "testing.."

Run playbook: ansible-playbook -i inventory playbook.yml

EXPECTED RESULTS

Warning that /usr/bin/env is no longer supported for ansible_python_interpreter. (See http://docs.ansible.com/ansible/intro_inventory.html)

ACTUAL RESULTS

Seeing MODULE FAILURE and OSError: [Errno 2] No such file or directory.

Full output:

% ansible-playbook -vvvv -i inventory playbook.yml
Using /Users/jladd/.ansible.cfg as config file

Confirmed that this was working in almost all versions prior to 2.1.x. Looks like the issue is inside the python code template used for ziploader.

A quick patch ...

@jladdjr Good catch. See if #15638 fixes things for you.

jladdjr · 2016-04-28T04:13:33Z

@abadger - awesome, thanks - should I check this while it's on your branch or wait for it to get merged into devel?

abadger · 2016-04-28T13:51:06Z

@jladdjr I've just merged it, go ahead and test from devel.
