Install Command Line Interface for openstack on MacOSX Sierra 10.12.5

The documents present in the openstack server to install Command Line Interface are not uptodate for MacOSX:
https://docs.openstack.org/user-guide/common/cli-install-openstack-command-line-clients.html

 Here is the solution. It has been tested in Sierra 10.12.5.

First be sure that you have python install. In terminal, enter:

belinda:~ marcgirondot$ python --version

Python 2.7.13

Any version higher than 2.7 should work. If you have not, when installing Xcode, python should be included.

Install Xcode from app store (take care, it is 4 GB !)

Open Xcode from application folder and install line command tools in terminal:

sudo xcode-select --install

Validate the installation in terminal using:

sudo xcodebuild -license

Install pip:
sudo easy_install pip

Upgrade pip:
sudo -H pip install --upgrade pip --ignore-installed six

Install different components of openstack:

# Installation 

sudo -H pip install python-openstackclient --ignore-installed six

sudo -H pip install --upgrade python-novaclient --ignore-installed six

sudo -H pip install --upgrade python-cinderclient --ignore-installed six

sudo -H pip install --upgrade python-neutronclient --ignore-installed six

sudo -H pip install --upgrade python-glanceclient --ignore-installed six

# for nova

sudo -H pip install --upgrade netifaces --ignore-installed six

To run it, you must define environment variables as described here:
https://docs.openstack.org/user-guide/common/cli-set-environment-variables-using-openstack-rc.html

It works for me !

To upgrade openstack client:
sudo -H pip install --upgrade python-openstackclient --ignore-installed six
