Ansible EC2 inventory on Mac

# When you need to run the AWS inventory tasks from ansible on
# a Mac Mojave, you may run into environment issues, especially if you're
# like me and can't remember whether or not to run pip as root,
# which pip to run, and which tools require python2 vs python3.
#
# With ansible, I've stopped using homebrew as the installer,
# and instead install it with pip.
#
# Use the python virtualenv mechanism to set up python dependencies,
# it's well worth the effort.

# General Troubleshooting for Python on Mac 
#
# If you messed up permissions somewhere by running pip/pip3 as root,
# chown -R $USER ~/Library/Caches/pip
# chown -R $USER ~/Library/Python
#
# With Python 3.7:
# 
# If you have issues with the cryptography package, you may need to expose the
# openssl libs and headers
# pip install -r requirements.txt --global-option=build_ext \
# 	--global-option="-L/usr/local/opt/openssl/lib" \
# 	--global-option="-I/usr/local/opt/openssl/include"
# 
# enum34 will break on Python > 3.4, so use enum-compat==0.0.2 
# PyYAML<3.13 will break in Python 3.7, so use PyYAML==3.13

# For Python 3:
# Begin by install virtualenv
pip3 install virtualenv

# Have virtualenv create a python install in some directory, here
# we're calling it venv
virtualenv venv

# this will create a python install in "venv/"
# source "activate" to modify your path so the preferred python is first
# this will also alter your shell prompt for the duration
source venv/bin/activate

# if you happen to have a requirements.txt, you can install with
pip install -r requirements.txt
