Assuming you have the required basic tools available, run this bash script:

#!/usr/bin/env bash
# Maintains a directory of Ansible virtual environments, and
# an accompanying snippet of bash aliases to activate them.
# Put the following into your .bash_rc to be able to use the aliases:
# source ~/.bash_ansible
BASH_SNIPPET="$HOME/.bash_ansible"
ANSIBLES="$HOME/.ansible_virtualenvs"
# Update this to keep regularly to have the latest of each minor version
VERSIONS="2.1.6 2.2.3 2.3.3 2.4.6 2.5.10 2.6.6 2.7.0"
# Needed for the projects we work on
MODULES="python-keyczar jmespath netaddr dnspython boto botocore boto3 natsort"
# Switch between different python versions. Remember to wipe the old virtualenvs if you do this.
PYTHON="python"
if [ ! -d "$ANSIBLES" ]; then
echo "Ansible collection directory $ANSIBLES does not exist yet, creating it."
mkdir -v $ANSIBLES
fi
echo "# Generated at `date` from $0" > $BASH_SNIPPET
for v in $VERSIONS; do
virtualenv -p "$PYTHON" "$ANSIBLES/ansible-$v"
source "$ANSIBLES/ansible-$v/bin/activate"
pip install ansible==$v $MODULES
deactivate
echo "alias ansible-activate-$v='source $ANSIBLES/ansible-$v/bin/activate'" >> $BASH_SNIPPET

When this finishes, open up a new terminal and start typing ansible-activate When this finishes, you can just start typing ansible-activate and use tab completion to pick the specific version.
Obviously you can use ansible to install ansible - for instance onto a deployment VM or bastion host:

| language | bash |
|---|---|
| theme | Midnight |

This works for Linux distros as well - each distro does require it's own preparations:
| Distro | Requirements |

| CentOS7 | |
