具有无头镀铬的设置硒错误：WebDriverException：消息：未知错误：Chrome无法启动：异常退出

Question

我正在尝试在以下环境中使用无头铬运行硒：作业系统：Ubuntu 16.04.6Chrome：77.0.3865.90（正式版本）（64位）ChromeDriver：77.0.3865.40硒服务器版本：3.141.59，修订版：e82be7d358

我一直在developer.google.com读过它，并关注推荐的Running Selenium with Headless Chrome帖子。我按照ipython REPL中的步骤操作：

from selenium import webdriver

options = webdriver.ChromeOptions()

options.binary_location = '/usr/local/bin'

options.add_argument('headless')

options.add_argument('window-size=1200x600')

driver = webdriver.Chrome(chrome_options=options)

但是这导致以下错误：

WebDriverException                        Traceback (most recent call last)

我一直在四处寻找this答案。我已经看到'headless'参数是这样传递的：add_argument("--headless")。我尝试将其与'--'相加，但结果相同。在this comment中也建议使用--no-sandbox参数，但是在我的情况下，添加此参数也不会改变任何内容。

我如何调试和修复此错误？

Answer 1

多个更改，完整路径

options.binary_location = '/usr/local/bin/chromedriver'



options.add_argument('--headless')

要设置分辨率，我将在初始化驱动程序对象之后使用它

driver.set_window_size(1280, 1024)
