WebDriverException:消息:未知错误:Chrome启动失败:使用ChromeDriver Chrome和Selenium Python异常退出错误
我正试图在我的虚拟ubuntu外壳上安装和使用Selenium chromedriver,我一步一步地学习各种教程,但似乎仍然有一些地方出了问题。。。在对这个问题进行了很多研究之后,我找不到任何答案 下面是我正在尝试运行的小代码:WebDriverException:消息:未知错误:Chrome启动失败:使用ChromeDriver Chrome和Selenium Python异常退出错误,python,selenium,google-chrome,selenium-webdriver,selenium-chromedriver,Python,Selenium,Google Chrome,Selenium Webdriver,Selenium Chromedriver,我正试图在我的虚拟ubuntu外壳上安装和使用Selenium chromedriver,我一步一步地学习各种教程,但似乎仍然有一些地方出了问题。。。在对这个问题进行了很多研究之后,我找不到任何答案 下面是我正在尝试运行的小代码: from selenium import webdriver from selenium.webdriver import Chrome from selenium.webdriver.chrome.options import Options chrome_opt
from selenium import webdriver
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-extensions')
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('https://google.com')
我添加了chrome_选项,这要感谢我在各种主题上找到的建议。但是我真的不明白为什么有必要
不幸的是,我的程序向我发送了以下错误,我被卡住了,不知道该怎么办:

有人已经有过这个问题或对此有什么建议吗?经验法则
Chrome在启动期间崩溃的一个常见原因是在Linux上以root用户管理员身份运行Chrome。虽然在创建WebDriver会话时可以通过传递-no-sandbox标志来解决此问题,但这种配置不受支持,并且非常不推荐。您需要将您的环境配置为以普通用户身份运行Chrome
这是第一条错误消息

您可以在ubuntu服务器上运行selenium crawler,该服务器上没有GUI,没有可用的X窗口,并带有以下代码段:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
driver = webdriver.Chrome(executable_path='/usr/lib/chromium-browser/chromedriver', options=chrome_options)
driver.get('https://google.com')
我在谷歌上搜索ruby错误,但发现了这个。对一些人来说,这可能是有帮助的 我错误地设置了依靠硒的水豚会话 错误的 session=Capybara::session.new:selenium\u chrome 正确,请参见添加的headless session=Capybara::session.new:selenium\u chrome\u headless
这回答了你的问题吗?你找到解决这个问题的办法了吗?我在Ubuntu20VPS中遇到了同样的问题,到目前为止,我唯一得到的是,由于Ubuntu20VPS没有安装GUI,除了通过无头论证之外,它不能使用chromedriver。谢谢你的反馈!我按照您的建议更改了参数,但同样的错误正在发生。我的操作系统是windows,但我在windows商店用Ubuntu操作jupyter笔记本,我下载了linux chromedriver。你认为这能解释这个错误吗?@LouisClisson如果底层操作系统是Ubuntu,我想你是对的。你能签出更新的答案并告诉我状态吗。
