Running Selenium WebDriver python bindings in chrome

Question

You need to make sure the standalone ChromeDriver binary (which is different than the Chrome browser binary) is either in your path or available in the webdriver.chrome.driver environment variable.

see http://code.google.com/p/selenium/wiki/ChromeDriver for full information on how wire things up.

Edit:

Right, seems to be a bug in the Python bindings wrt reading the chromedriver binary from the path or the environment variable. Seems if chromedriver is not in your path you have to pass it in as an argument to the constructor.

import os
from selenium import webdriver

chromedriver = "/Users/adam/Downloads/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)
driver.get("http://stackoverflow.com")
driver.quit()

For Linux

1. Check you have installed latest version of chrome brwoser-> chromium-browser -version

2. If not, install latest version of chrome sudo apt-get install chromium-browser

3. get appropriate version of chrome driver from here

4. Unzip the chromedriver.zip

5. Move the file to /usr/bin directory sudo mv chromedriver /usr/bin

6. Goto /usr/bin directory cd /usr/bin

7. Now, you would need to run something like sudo chmod a+x chromedriver to mark it executable.

8. finally you can execute the code.

   from selenium import webdriver
   
   driver = webdriver.Chrome()
   driver.get("http://www.google.com")
   print driver.page_source.encode('utf-8')
   driver.quit()
   

Mac OSX only

An easier way to get going (assuming you already have homebrew installed, which you should, if not, go do that first and let homebrew make your life better) is to just run the following command:

brew install chromedriver

That should put the chromedriver in your path and you should be all set.

For windows

Download ChromeDriver from this direct link OR get the latest version from this page.

Paste the chromedriver.exe file in your C:\Python27\Scripts folder.

This should work now:

from selenium import webdriver
driver = webdriver.Chrome()
