In case you are using Buildout  you can easily automate the installation processes that Pykler describes using the gp recipe node recipe    nodejs  recipe   gp recipe node version   0 10 32 npms   phantomjs scripts   phantomjs   That part installs node js as binary  at least on my system  and then uses npm to install PhantomJS  Finally it creates an entry point bin phantomjs  which you can call the PhantomJS webdriver with   To install Selenium  you need to specify it in your egg requirements or in the Buildout configuration    driver   webdriver PhantomJS  bin phantomjs

The answer by  Pykler is great but the Node requirement is outdated  The comments in that answer suggest the simpler answer  which I ve put here to save others time    Install PhantomJS  As  Vivin-Paliath points out  it s a standalone project  not part of Node   Mac   brew install phantomjs   Ubuntu   sudo apt-get install phantomjs   etc Set up a virtualenv  if you haven t already    virtualenv mypy    doesn t have to be  mypy   Can be anything    mypy bin activate   If your machine has both Python 2 and 3 you may need run virtualenv-3 6 mypy or similar  Install selenium   pip install selenium  Try a simple test  like this borrowed from the docs   from selenium import webdriver from selenium webdriver common keys import Keys  driver   webdriver PhantomJS   driver get  http   www python org   assert  Python  in driver title elem   driver find element by name  q   elem clear   elem send keys  pycon   elem send keys Keys RETURN  assert  No results found   not in driver page source driver close

PhantomJS recently dropped Python support altogether  However  PhantomJS now embeds Ghost Driver   A new project has since stepped up to fill the void  ghost py  You probably want to use that instead   from ghost import Ghost ghost   Ghost    with ghost start   as session      page  extra resources   ghost open  http   jeanphi me       assert page http status  200 and  jeanphix  in ghost content

this is what I do  python3 3   I was processing huge lists of sites  so failing on the timeout was vital for the job to run through the entire list   command    phantomjs --ignore-ssl-errors true    lt your js file for phantom gt  process   subprocess Popen command  shell True  stdout subprocess PIPE     make sure phantomjs has time to download process the page   but if we get nothing after 30 sec  just move on try      output  errors   process communicate timeout 30  except Exception as e      print   t tException   s    e      process kill      output will be weird  decode to utf-8 to save heartache phantom output      for out line in output splitlines        phantom output    out line decode  utf-8

Now since the GhostDriver comes bundled with the PhantomJS  it has become even more convenient to use it through Selenium   I tried the Node installation of PhantomJS  as suggested by Pykler  but in practice I found it to be slower than the standalone installation of PhantomJS  I guess standalone installation didn t provided these features earlier  but as of v1 9  it very much does so     Install PhantomJS  http   phantomjs org download html   If you are on Linux  following instructions will help https   stackoverflow com a 14267295 382630  Install Selenium using pip    Now you can use like this  import selenium webdriver driver   selenium webdriver PhantomJS   driver get  http   google com     do some processing  driver quit
