How to properly stop phantomjs execution

Question

I initiated and close phantomjs in Python with the following

from selenium import webdriver    
driver = webdriver.PhantomJS()
driver.get(url)
h         


        

Answer 1

As of July 2016, driver.close() and driver.quit() weren't sufficient for me. That killed the node process but not the phantomjs child process it spawned.

Following the discussion on this GitHub issue, the single solution that worked for me was to run:

import signal

driver.service.process.send_signal(signal.SIGTERM) # kill the specific phantomjs child proc
driver.quit()                                      # quit the node proc
