[PhantomJS] how to install PhantomJS

source: http://stackoverflow.com/questions/13287490/is-there-a-way-to-use-phantomjs-in-python

The easiest way to use PhantomJS in python is via Selenium. The simplest installation method is

1. Install NodeJS
2. Using Node's package manager install phantomjs: npm -g install phantomjs
3. install selenium (in your virtualenv, if you are using that)

After installation, you may use phantom as simple as:

from selenium import webdriver

driver = webdriver.PhantomJS() # or add to your PATH
driver.set_window_size(1024, 768) # optional
driver.get('https://google.com/')
driver.save_screenshot('screen.png') # save a screenshot to disk
sbtn = driver.find_element_by_css_selector('button.gbqfba')
sbtn.click()

If your system path environment variable isn't set correctly, you'll need to specify the exact path as an argument to webdriver.PhantomJS(). Replace this:

driver = webdriver.PhantomJS() # or add to your PATH

... with the following:

driver = webdriver.PhantomJS(executable_path='/usr/local/lib/node_modules/phantomjs/lib/phantom/bin/phantomjs')

While I was trying to install phantomjs on Ubuntu 13.10, I'd gotten into severl troubles.

In a nutshell, just issue the following command on *nix terminal:

$ sudo apt-get install nodejs npm nodejs-lagacy libfontconfig1 && sudo npm -g install phantomjs

1. nodejs 설치

2. npm 설치

3. nodejs-legacy설치

4. libfontconfig1 설치
