python - 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)
html_doc = driver.page_source
driver.close()

yet after the script ends execution I still find an instance of phantomjs in my Mac Activity Monitor. And actually every time I run the script a new process phantomjs is created.

How should I close the driver?

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
