Question

我已经安装了Python 3.6.2，3.5.0硒与GeckoDriver和0.18.0火狐版本54.0.1version在Windows 7我试图运行硒脚本正在加载一个Firefox，我得到与Firefox版本错误不匹配。请让我知道是什么问题。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") 

错误消息返回：

当你与Python 3.6.2工作，Selenium 3.5.0与GeckoDriver 0.18.0和Firefox浏览器的版本是54.0.1上Windows 7，你不能属性marionette设置为False。强制将marionette设置为False将引发WebDriverException。所以，无论是你必须接受的["marionette"] = True默认设置，也可以明确设置["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")
