问题描述

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

Chrome version: 68.0.3440.106
Chrome webdriver version: ChromeDriver 2.41.578737
Python Version : Python 3.5.2

我用python写了这段代码:

I write this code in python:

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:

after few seconds chrome opened with this error:


直到我关闭 chrome 并得到这个异常，什么都没有发生:


and nothing happend till i close chrome and get this exception:

解决方案

我最近在使用 TeamCity 时遇到了这个问题，这是由于 chrome(和 chromedriver)在执行我的脚本后没有关闭造成的.插入taskkill/f/im chrome.exe"和taskkill/f/im chromedriver.exe"修复了这个问题.

I recently had this issue using TeamCity, which was caused by chrome (and chromedriver) not shutting down after executing my script. inserting "taskkill /f /im chrome.exe" and "taskkill /f /im chromedriver.exe" fixed this issue.
