Mac OSX Install Guide

Using virtualenv is the recommended way for working on Mac OSX

Using Python Virtualenv

virtualenv is a tool to create isolated Python environments.

1. Install Homebrew

Paste that at a Terminal prompt.

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
2. Using Homebrew install Python and pip

First, create a new virtualenv called "ryu_venv":

$ brew install python

Then pip will work.

3. Install the virtualenv

Using pip install virtualenv.

$ pip install virtualenv

4. Setup virtualenv

First, create a new virtualenv called "ryu_venv":

$ virtualenv ryu_venv

Activate the newly created virtualenv:

$ source ./ryu_venv/bin/activate

Your shell prompt will now display the currently active virtualenv:

(ryu_venv)$

5. Install the Ryu packages
(ryu_venv)$ STATIC_DEPS=true pip install lxml
(ryu_venv)$ pip install greenlet
(ryu_venv)$ pip install ryu
6. Starting Ryu

Once you have properly setup virtualenv and install ryu, you can start ryu using following command:

(ryu_venv)$ ryu-manager

You may need to clone official source code for running sample application.

$ git clone https://github.com/osrg/ryu.git

Running a sample application

(ryu_venv)$ ryu-manager ./ryu/ryu/ryu/app/simple_switch_13.py

7. Deactivate virtualenv

If you want to leave python virtualenv just using deactivate command.

(ryu_venv)$ deactivate
