Issue with pip module

Hello,

I'm having a bit of trouble with the PIP module re-installing things
that are there already...

When I try to install simplejson with the specified version (which is
already installed), Ansible correctly indicates there's nothing to do
and reports changed:false after a second or two.

ansible -vvv -s -u vagrant sushi.mens.de -m pip -a 'name=simplejson virtualenv=/opt/graphite version=2.6.2'
<127.0.0.1> ESTABLISH CONNECTION FOR USER: vagrant on PORT 2222 TO 127.0.0.1
<127.0.0.1> EXEC /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-1352922428.2-29240188583008 && chmod a+rx $HOME/.ansible/tmp/ansible-1352922428.2-29240188583008 && echo $HOME/.ansible/tmp/ansible-1352922428.2-29240188583008'

sushi.mens.de | success >> {
    "changed": false,
    "cmd": null,
    "name": "simplejson",
    "requirements": null,
    "state": "present",
    "version": "2.6.2",
    "virtualenv": "/opt/graphite"
}

On the other hand, if I try to install 'carbon', Ansible reports
changed:true every time: PIP actually downloads and installs this
module.

ansible -vvv -s -u vagrant sushi.mens.de -m pip -a 'name=carbon virtualenv=/opt/graphite version=0.9.10'
<127.0.0.1> ESTABLISH CONNECTION FOR USER: vagrant on PORT 2222 TO 127.0.0.1

sushi.mens.de | success >> {

    "name": "carbon",
    "requirements": null,
    "state": "present",
    "version": "0.9.10",
    "virtualenv": "/opt/graphite"
}

Is this the fault of Ansible's PIP module, Python PIP, or is it due to
how the 'carbon' module is defined/built/packaged.

Anybody have a clue?

Thanks,

This is a really old thread, but wondering if anyone had any solutions for this issue.

Encountered with both requirements.txt and an individual package:

- name: install requirements
  sudo: no
  pip:
    requirements: /srv/<project>/requirements.txt
    virtualenv: /home/sam/.virtualenvs/<project>/

- name: install raven
  sudo: no
  pip:
    name: raven
    version: 1.9.4
    virtualenv: /home/sam/.virtualenvs/<project>/

with ansible-playbook -vvv for the simpler case of installing raven, though both outputs contained reinstalling simplejson (then made readable with print and hand editing):

changed: [<hostname>] =>
{
  "changed": true,
  "cmd": "/home/sam/.virtualenvs/<project>/bin/pip install --use-mirrors raven==1.9.4",
  "item": "",

  "requirements": null,
  "state": "present",

This is after:
