Installing rvm with Ansible playbook

I’m learning Ansible and am trying to install rvm with the rvm_io.rvm1-ruby playbook.

It’s failing to create /usr/local/rvm, even though I’m telling it to use sudo.

Has anyone used this playbook successfully, and if so, could you point out what I’m doing wrong please?

Here’s my playbook so far:

---
- name: Install everything
  hosts: "{{ hosts }}"
  remote_user: someone
  sudo: yes

  roles:
    - mysql

    - role: rvm_io.rvm1-ruby
      sudo: True
      rvm1_user: 'someone'
      rvm1_rvm_version: 'stable'
      rvm1_rvm_check_for_updates: True
      rvm1_rubies:
        - '{{ ruby_version }}'

I’ve tried executing both with and without ‘sudo: True’ in the rvm role and the result is the same (I’m assuming sudo should still be active from the initial "sudo: yes’?)

I’m specifying the sudo pwd on the cmd line using -K and the install/configure mysql is working OK, so sudo is definitely being used for that.

If I SSH in as ‘someone’ and

$ sudo mkdir /usr/local/rvm

there’s no problem either.

Thanks!
