title: Reload PATH for the entire playbook
body: <p>As part of most of the Ansible playbooks I need to install Node and Mongo from internally hosted tarballs. Sudo privileges and internet access are not available. All of the Ansible runs happen against localhost.</p>
  
  <p>One of the problems of this setup is that after untarring node/mongo, they need to be added to PATH or subsequent roles/tasks won't be able to rely on them. Unfortunately, I don't seem to be able to find a way to amend PATH within an Ansible playbook run. </p>
  
  <p>I've tried using shell and command tasks to export PATH and source .bashrc, neither of those seem to help. Is there a way to use my node installation within the same playbook? yum task seems to do the trick, but it's not available to me now.</p>
