Hi,

I am trying to create a custom module based on pyrax (rackspace) to create reverse dns entries. I followed the hacking guide but I am stuck testing the new module because of an AttributeError: ‘module’ object has no attribute ‘ModuleReplacer’ error.

My set up is as follows:

Mac OSX, installed python with brew and using pip for the dependencies. Local python is at /usr/local/bin/python. Then I following the hacking guide at [The Manifesto for Agentic Automation](http://www.ansibleworks.com/docs/developing_modules.html) and checked out ansible, ran ./hacking/env-setup and than:

./hacking/test-module -m ../servers/modules/rax\_dns

Output:

Traceback (most recent call last):

File “./hacking/test-module”, line 163, in

main()

File “./hacking/test-module”, line 147, in main

(modfile, module\_style) = boilerplate\_module(options.module\_path, options.module\_args)

File “./hacking/test-module”, line 84, in boilerplate\_module

replacer = module\_common.ModuleReplacer()

The rax\_dns:

#!/usr/bin/python #changing this to /usr/local/bin/python has no effect.

import pyrax

def main():

module = AnsibleModule(

argument\_spec = dict(

credentials = dict(required=True),

hostname = dict(required=True)

)

)

pyrax.set\_setting(“identity\_type”, “rackspace”)

pyrax.set\_credential\_file(credentials)

# include magic from lib/ansible/module\_common.py

#\<\<INCLUDE\_ANSIBLE\_MODULE\_COMMON\>\>

main()

What am I missing? Also can I put my custom modules in my own project? Or do they need to be in the ansible directory?

Lars
