Bug Report

Ansible Version:

ansible 2.0.0 (devel 2963bba901) last updated 2015/10/14 15:07:35 (GMT +300)
  lib/ansible/modules/core: (devel 95b10c9fdd) last updated 2015/10/14 10:52:54 (GMT +300)
  lib/ansible/modules/extras: (devel 15480e3d04) last updated 2015/10/14 10:52:56 (GMT +300)
  config file = /etc/ansible/ansible.cfg
  configured module search path = None

Ansible Configuration:

Issue exists even with the github version of ansible.cfg

Environment:

MacOSX Yosemite 10.10.5

Summary:

In most recent devel usage of ec2 module is broken. Trying to use even the basic examples from the ec2_module -page produces message:

 fatal: [localhost]: FAILED! => {"failed": true, "msg": "ERROR! module is missing interpreter line"}

The error happens even before the module options are parsed.

The functionality has been broken since commit 18e2ee16ef0895831ead312550eb5de44c99524c . I couldn't decipher why that commit broke the ec2 module.

Steps To Reproduce:

- hosts: localhost
  tasks:
   - ec2:
      key_name: mykey
      instance_type: t2.micro
      image: ami-123456
      wait: yes
      group: webserver
      count: 3
      vpc_subnet_id: subnet-29e63245
      assign_public_ip: yes

Expected Results:

ec2 modules should function as before and allow creation of instances.
Actual Results:

Following error is printed and playbook execution ends.

fatal: [localhost -> localhost]: FAILED! => {"failed": true, "msg": "ERROR! module is missing interpreter line"}

Unable to replicate. This error is indicating the module does not have the required path, but it in fact does: https://github.com/ansible/ansible-modules-core/blob/devel/cloud/amazon/ec2.py#L1

Might be due to a path issue and/or setup issue. Does this happen with other modules?

I finally solved the bug. I had ec2.ini in 'library' -directory and for some reason ansible was picking it when it looked for ec2 -module. Renaming the ec2.ini to ec2_dynamic_inventory.ini and executing 'export EC2_INI_PATH=library/ec2_dynamic_inventory.ini' fixed the problem.

Just a note, you can get this error if you're missing the:

#!/usr/bin/python

hashbang at the top of your module file. Probably only relevant for people who are developing their own modules. But it tripped me up!
