python - 该进程从 chrome 位置 C :\. 开始。\Chrome\Application\chrome.exe 不再运行，因此 ChromeDriver 假设 Chrome 已崩溃

Question

Chrome 版本:68.0.3440.106
Chrome 网络驱动程序版本:ChromeDriver 2.41.578737
Python 版本:Python 3.5.2

我用 python 编写这段代码:

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


o = webdriver.ChromeOptions()
o.add_argument("disable-extensions");
o.add_argument("--start-maximized");
driver = webdriver.Chrome(executable_path=r"chromedriver.exe",options=o)
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

几秒钟后 chrome 打开并出现此错误:

在我关闭 chrome 并得到这个异常之前什么都没有发生:

    Traceback (most recent call last):
  File ".../game.py", line 8, in <module>
    driver = webdriver.Chrome(executable_path=r"chromedriver.exe",options=o)

  (The process started from chrome location C:\Program Files (x86)\Google\Chrome\Application\chrome.exe is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

使用正确的参数来禁用扩展:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
o = Options()
#o.add_argument("--disable-extensions"); #here
o.add_experimental_option("useAutomationExtension", false); #you can try this as well
o.add_argument("--start-maximized");
driver = webdriver.Chrome(executable_path=r"chromedriver.exe",chrome_options=o)
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()
