How to install python3.x with ansible?

Solution

Rather than using the shell module to set environment variables on the remote host, Ansible has the environment keyword, which can set per task or even per playbook.

Assuming the www user already exists I managed to get this working with some more specific path setting:

- name: enable pyenv and install python
  shell: /home/www/.pyenv/bin/pyenv init - && /home/www/.pyenv/bin/pyenv install 3.4.3 chdir=/home/www
  environment:
    pyenv_root: /home/www/.pyenv
    path: "{{ pyenv_root }}/bin:$PATH"
  become: yes
  become_user: www

You will need to run the playbook with:

ansible-playbook --ask-become-pass <playbook-name>

and supply the password for the www user on request.

If that doesn't work, you might have to post the whole playbook here for us to look at :)
