First, let me introduce something about develop environment, such as Brew, easy_install,RVM, … etc.

Mac Develop Environment

Homebrew: The missing package manager for OS X

$ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

with brew, you can install anything in command. eg:

$brew install lighttpd

Easy_install

Download the appropriate egg for your version of Python (e.g. setuptools-0.6c9-py2.4.egg). Do NOT rename it. Run it as if it were a shell script, e.g. sh setuptools-0.6c9-py2.4.egg. Setuptools will install itself using the matching version of Python (e.g. python2.4), and will place the easy_install executable in the default location for installing Python scripts (as determined by the standard distutils configuration files, or by the Python installation).

with this, you can install anything abou python package in command. eg:

easy_install xxx

BTW: You can check package info in “/Library/Python/2.7/site-packages”

RVM: Ruby Version Manager

$ \curl -L https://get.rvm.io | bash -s stable --ruby

Common Python Library

1, NLP:

nltk: http://nltk.org/

chinese word segment https://github.com/fxsjy/jieba

2, Machine Learning

scikit_learn: https://pypi.python.org/pypi/scikit-learn/

However,ML’s scikit-learn lib have to depend on lots of other package(scipy….) Here is a good scipt for mac 10.8 user http://fonnesbeck.github.com/ScipySuperpack/

the scipt code :

#!/bin/sh
PYTHON='/usr/bin/python'
GIT_FILENAME='git-1.7.7.3-intel-universal-snow-leopard'

SUDO='sudo'

if [ -z "$VIRTUAL_ENV" ]; then
    # Standard Python env
    PYTHON=/usr/bin/python
    SUDO=${SUDO}
else
    # Virtualenv
    PYTHON=python
    SUDO="" #${SUDO} is not required in a virtualenv

    SUPERPACK_PATH='.'

else
    
    SUPERPACK_PATH='ScipySuperpack'
