python - Selenium Firefox webdriver results in error: Service geckodriver unexpectedly exited. Status code was: 2

Question

I'm writing a program that will search a website for specific entries inside of articles, I'm using selenium webdriver for Python.

While attempting to connect to the site I get this exception:

Traceback (most 
recent call last):
  File "search.py", line 26, in <module>
    test.search_for_keywords()
  File "search.py", line 13, in search_for_keywords
    browser = webdriver.Firefox()

    self.service.start()

    % (self.path, return_code)
selenium.common.exceptions.WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 2

It's saying that the webdriver unexpectedly exited. How can I fix this issue? I'm trying to connect with firefox version 48.0 with python version 2.7.12

Running python selenium tests in latest Firefox browser (Version 47 above)

“Marionette" or "Gecko Driver” is the future version of firefox driver. Firefox 47+ is not compatible with the driver used in Selenium 2.53, and Selenium 3+ will be using a new driver called "Marionette" or "Gecko Driver" (which isn't officially released yet).

Prerequisites:

? Mozilla firefox : Version 50.0.2(Version 47 above)

? Selenium : Version 3.0.2

? Geckodriver : Version 0.11.1

? Python : Version 2.7.3

Setup:

? Selenium : pip install –U selenium

? Geckodriver : Download the geckodriver from https://github.com/mozilla/geckodriver/releases , unzip the file and place it in a folder

? Set the ‘Path’ environment variable with geckodriver path

Sample script:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

#Provide the Firefox binary path

binary = FirefoxBinary(r'C:Program Files (x86)Mozilla Firefoxfirefox.exe’)

caps = DesiredCapabilities.FIREFOX.copy()

#Set ‘marionette’ browser to True

caps['marionette'] = True

#Launch the Firefox instance by specifying the geckodriver executable path

driver = webdriver.Firefox(firefox_binary=binary,capabilities=caps, executable_path`='D:/Installers/geckodriver-v0.11.1-win64/geckodriver')

You are done ...!
