Install Ansible 2.0+ on Amazon AMI

Today, while upgrading some of my Ansible roles I’ve hit the problem.  Some of the newer roles require Ansible 2.0.  My Amazon AMI machine that runs the playbooks was still on version 1.9.  EPEL repository doesn’t seem to have the newer Ansible version yet.  Gladly, Google brough in this StackOverflow thread, which suggested installing Ansible with pip, not with yum.  This helped a lot:

rpm -e ansible
pip install ansible

It actually brought in Ansible v2.2 (see also Ansible v2.1), which is even better.
