# Ansible playbook: install pyenv v201506210608
# Louis T. Getterman IV (@LTGIV)
# www.GotGetLLC.com / www.opensour.cc/ggcom/ansible/playbooks/pyenv
#
# Example Usage:
# [user@host ~$] ansible-playbook ~/ggcom/ggcom-ansible-playbooks/ubuntu/pyenv.yml --extra-vars 'target=nameFromHostsFile user=nameOfUserUsingPyenv'
#
# Skip the prerequisites and go straight for the meat and potatoes:
# [user@host ~$] ansible-playbook ~/ggcom/ggcom-ansible-playbooks/ubuntu/pyenv.yml --extra-vars 'target=nameFromHostsFile user=nameOfUserUsingPyenv' --tags skipprereq
# 
# See available versions for installing:
# [user@host ~$] pyenv install --list
#
# Setup a temporary directory using 1 of 2 methods (some VPS don't allow /tmp which mktemp tends to use)
# [user@host ~$] export TMPDIR=`mktemp -d 2>/dev/null || mktemp -d -t 'dfwu'`
# [user@host ~$] mkdir -pv "$HOME/tmp"; export TMPDIR="$HOME/tmp";
#
# Install a Python version (most common choices are latest Python 2 or Python 3):
# (the following version number is the most recent for Python 2 at the time of this file being pushed to GitHub)
# [user@host ~$] pyenv install 2.7.9
#
# Create Python virtual environment 
# [user@host ~$] pyenv virtualenv 2.7.9 my-virtual-env-Py2
#
# Setup virtual environment as global (or local)
# [user@host ~$] pyenv global my-virtual-env-Py2
#
# Thanks:
#
# pyenv install for CentOS 6.5 x86_64
