FreeBSD Selenium PhantomJS - 서비스에 연결할 수 없습니다.

나는 PhantomJS를 실행하기 위해 셀레늄을 사용해야 한다고 주장합니다. 그래서 FreeBSD Jail을 준비하고 포트를 통해 phantomjs를 설치했습니다.

whereis phantomjs
> phantomjs: /usr/local/bin/phantomjs /usr/ports/lang/phantomjs

/usr/local/bin/phantomjs -v
> 2.0.0

내 스크립트는 다음과 같습니다

from selenium import webdriver

PHANTOM_PATH = '/usr/local/bin/phantomjs'

driver = webdriver.PhantomJS(executable_path=PHANTOM_PATH)
driver.set_window_size(1024, 768)
driver.get('https://google.com/')
driver.save_screenshot('screen.png')
driver.quit()

그런데 이런 오류가 계속 발생하고 해결책을 찾을 수 없습니다.

File "driver.py", line 5, in <module>
driver = webdriver.PhantomJS(PHANTOM_PATH)
