phantomJS: "'Service' object has no attribute '_log'"

[Peter Nguyen]

Hi,

I'm using selenium for web testing with PhantomJS, this simple code runs super fine on local machine (ubuntu 14.4) or in python console on server (VPS ubuntu 14.4).
Selenium 2.44, phantom 1.98, nginx 1.4.6, gunicorn 19.11. However, when I try to call it from a flask application, it throws these error:

Code:

from flask import Flask, request
from selenium import webdriver

app = Flask(__name__)
app.debug = True

@app.route("/test")
def test():
    url = "http://www.google.com"
    driver = webdriver.PhantomJS('./phantomjs')
    driver.get(url)
    result = driver.page_source
    driver.close()
    return result

if __name__ == "__main__":
  app.run() 

the server throws an AtrributeError Exception:

Exception AttributeError: "'Service' object has no attribute '_log'" in <bound method Service.__del__ of <selenium.webdriver.phantomjs.service.Service object at 0x7fcc6eb18710>> ignored

I tried to run it with both root and other admin accounts, the probelm still persists. Since I couldn't google this error so I post this here and hope someone can help.

Thank you
