无法在python中的selenium webdriver中加载firefox

Question

我已经在Windows 7上安装了Python 3.6.2,Selenium 3.5.0和GeckoDriver 0.18.0以及firefox版本54.0.1version.我正在尝试运行一个selenium脚本,它正在加载一个firefox版本错误与firefox版本不匹配.请告诉我这是什么问题.下面的代码和错误消息.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
capabilities = webdriver.DesiredCapabilities().FIREFOX
capabilities["marionette"] = False
binary = FirefoxBinary('C:/Users/gopalakrishnarr/Downloads/FirefoxPortable/App/Firefox/firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary, capabilities=capabilities, executable_path="C:/Users/gopalakrishnarr/AppData/Local/Programs/geckodriver-v0.18.0-win64/geckodriver.exe")
driver.get("http://www.google.com")

返回错误消息:

当你一起工作Python 3.6.2,Selenium 3.5.0与GeckoDriver 0.18.0和Firefox浏览器版本54.0.1上Windows 7,你可以不设置该属性marionette来False.强行设置marionette到False会引发一个WebDriverException.所以,无论是你必须接受的默认设置["marionette"] = True,也可以明确地设置["marionette"]到True如下:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

capabilities = webdriver.DesiredCapabilities().FIREFOX
capabilities["marionette"] = True
binary = FirefoxBinary('C:/Program Files/Mozilla Firefox/firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary, capabilities=capabilities, executable_path="C:/Utility/BrowserDrivers/geckodriver.exe")
driver.get("http://www.google.com")
