selenium.common.exceptions.WebDriverException:消息:未知错误

问题描述

这是我的代码脚本:

从 selenium 导入 webdriver选项 = webdriver.ChromeOptions()options.add_argument("user-data-dir=C:\Users\hadi\AppData\Local\Google\Chrome\User Data") #您的 chrome 配置文件的路径w = webdriver.Chrome(executable_path="E:Pythonchromedriver.exe", chrome_options=options)w.get("https://www.facebook.com")

在运行此脚本时出现此错误:

我已经编辑了 chromedriver 的可执行路径，但是当我运行脚本时，我的 chrome 驱动程序会打开，但之后会卡住 2-3 分钟，然后因上述以下错误而崩溃.

拇指规则

Chrome 在启动过程中崩溃的一个常见原因是作为 root 用户(administrator 运行 Chrome>) 在 Linux 上.虽然可以通过在创建 WebDriver 会话时传递 --no-sandbox 标志来解决此问题，但这种配置不受支持且不鼓励使用.您需要将环境配置为以普通用户身份运行 Chrome.

根据您的代码试验，您似乎正在尝试访问 Chrome 配置文件，因此您可以使用以下解决方案:

• 代码块:

  从 selenium 导入 webdriver从 selenium.webdriver.chrome.options 导入选项选项=选项()options.add_argument("user-data-dir=C:\path\to\your\profile\Google\Chrome\User Data\Profile 2")driver = webdriver.Chrome(executable_path=r'C:path	ochromedriver.exe', chrome_options=options)driver.get("https://www.google.co.in")

• 您可以在此处找到详细讨论 如何通过 Python 打开 Chrome 配置文件

This is my code script:

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\Users\hadi\AppData\Local\Google\Chrome\User Data") #Path to your chrome profile
w = webdriver.Chrome(executable_path="E:Pythonchromedriver.exe", chrome_options=options)
w.get("https://www.facebook.com")

and on running this script i'm getting this error:

Traceback (most recent call last):

    w = webdriver.Chrome(executable_path="E:\Python\chromedriver.exe", chrome_options=options)

I've edited my executeable path to chromedriver but when i run the script my chrome driver opens but after that stuck for 2-3minutes and then crashes with the above following error.

Thumb rule

A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.

As per your code trials seems you are trying to access a Chrome Profile so you can use the following solution:

• Code Block:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.add_argument("user-data-dir=C:\path\to\your\profile\Google\Chrome\User Data\Profile 2")
  driver = webdriver.Chrome(executable_path=r'C:path	ochromedriver.exe', chrome_options=options)
  driver.get("https://www.google.co.in")
