running mkvirtualenv using ansible

Question

I am provisioning a machine using ansible. I managed to install virtualenv and virtualenvwrapper fine on the vm. However, I can\'t seem to create a virtualenv on the vm.

Additionally to @SiggyF's excellent answer, I would like to add: In case that it appears that this ansible task fails, as it happens somehow with me, you can use the failed_when feature (ansible 1.4+):

- name: Make virtualenv
  shell: "./usr/share/virtualenvwrapper/virtualenvwrapper.sh && mkvirtualenv {{ project }} --python={{ python }} --no-site-packages"
  args:
    executable: /bin/bash
    creates: "{{ virtualenv_dir }}/{{ project }}"
  register: mkvirtualenv
  failed_when: 'mkvirtualenv.changed and "New python executable" not in mkvirtualenv.stdout'
