Do these first:

• Use virtualenv + virtualenvwrapper with Python

  $ pip install virtualenv
  $ pip install virtualenvwrapper
  

  # ~/.bash_profile
  
  # Enable virtualenvwrapper 
  VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
  export WORKON_HOME=~/Envs
  source /usr/local/bin/virtualenvwrapper.sh
  

  # Virtualenvwrapper-powershell in Windows
  PS> pip install virtualenvwrapper-powershell
  PS> $env:WORKON_HOME="~/Envs"
  PS> mkdir $env:WORKON_HOME
  PS> import-module virtualenvwrapper
  

  # Reload your profile
  $ source ~/.bash_profile
  # Create your env directory
  $ mkdir -p $WORKON_HOME
  

  # Create a new environment
  $ mkvirtualenv my-fresh-environment
  # Activate an environment
  $ workon my-fresh-environment
  # List environments
  $ lsvirtualenv
  # Remove an environment
  $ rmvirtualenv my-polluted-environment
  

   [full instructions]

Create your virtualenv. If you are using virtualenvwrapper, run:

$ mkvirtualenv ipy

This can be any environment name you choose. I call mine ipy for brevity. IPython has a bunch of dependencies and it's nice to have them all in ONE place rather than globally throughout your machine.

Then use pip to install the following.

• jinja2
• pyzmq
• tornado

$ workon ipy
$ pip install jinja2 pyzmq tornado ipython

Then, to run a local instance of IPython Notebook:

$ ipython notebook
