EDIT

I have found my problem

The problem is the log file generate by phantomjs and and shebang to top in my code like this

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import sys
from selenium import webdriver

driver =webdriver.PhantomJS( service_log_path='/home/ghostdriver.log'executable_path='/usr/local/bin/phantomjs')
driver.set_window_size(1024, 768)
driver.get(url)
page = driver.page_source.encode("utf-8")

print(page)

and after change the permission of the ghostdriver.log for the www-data can read id you have a error again put the group www-data in the sudoers file with no passwd
