아래를 참고하자.

 

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 http://chromedriver.storage.googleapis.com/index.html
4. Unzip the chromedriver.zip
5. Move the file to /usr/bin directory sudo mv chromedriver /usr/bin
6. Goto /usr/bin directory and you would need to run something like "chmod a+x chromedriver" to mark it executable. 
7. finally you can execute the code.

import os from selenium import webdriver from pyvirtualdisplay import Display display = Display(visible=0, size=(800, 600)) display.start() driver = webdriver.Chrome() driver.get("http://www.google.com") print driver.page_source.encode('utf-8') driver.quit() display.stop()
