无法在 python 中的 selenium webdriver 中加载 firefox

Question

我已经安装了 Python 3.6.2，Selenium 3.5.0 和 GeckoDriver 0.18.0，firefox 版本是 54.0.1 版本 windows 7. 我正在尝试运行一个正在加载 firefox 的 selenium 脚本，我在其中遇到与 firefox 版本不匹配的错误。请让我知道问题出在哪里。下面是代码和错误信息。

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")

返回错误信息：

当您使用 Python 3.6.2、Selenium 3.5.0 和 GeckoDriver 0.18.0 并且 Firefox 浏览器版本为 54.0.1 on Windows 7 时，您无法设置属性 marionette 到 False。将 marionette 强制设置为 False 将引发 WebDriverException。所以要么你必须接受 ["marionette"] = True 的默认设置，要么你可以明确地将 ["marionette"] 设置为 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")
