Web 驱动程序异常

Question

这是我使用的代码。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("https://172.16.16.16/24online/servlet/E24onlineHTTPClient")

当我尝试为 firefox 运行脚本时会发生此异常。
请帮我解决这个问题

Answer 1

当您使用 Selenium 3.4.3、geckodriver v.0.18.0、Mozilla Firefox 53.0 使用 Python 时，以下代码块将打开所需的 url：

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

binary = FirefoxBinary(r'C:\Program Files\Mozilla Firefox\firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get('https://stackoverflow.com')

升级 Firefox 应该可以解决这个问题，如果你想确定的话，你也可以尝试升级 selenium...
