如何使用Python Selenium WebDriver加载Chrome自定义配置文件？报错求助

我尝试使用Python Selenium WebDriver启动Chrome自定义配置文件，但运行时出现错误。已尝试添加--no-sandbox、--disable-dev-shm-usage、--remote-debugging-port=xxxx参数，但均无效。

我的代码： #

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
import time

options = webdriver.ChromeOptions()
options.add_argument("--profile-directory=Profile 6")
options.add_argument("--user-data-dir=C:/Users/SIM/AppData/Local/Google/Chrome/User Data")
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
time.sleep(3)

运行输出： #

解决方法： #

• 关闭所有Chrome进程
  错误提示里的Opening in existing browser session说明当前有Chrome实例在占用目标用户数据目录，Selenium无法获取控制权。打开任务管理器，结束所有chrome.exe和chromedriver.exe进程后再运行脚本。

• 修正路径格式（避免转义问题）
  将用户数据目录路径改为原始字符串格式，防止转义字符干扰：

  options.add_argument(r"--user-data-dir=C:\Users\SIM\AppData\Local\Google\Chrome\User Data")
  

• 添加初始化屏蔽参数
  加入--no-first-run和--no-default-browser-check，避免Chrome启动时的初始化弹窗打断会话创建：

  options.add_argument("--no-first-run")
  options.add_argument("--no-default-browser-check")
  

• 验证配置文件路径正确性
  确认Profile 6文件夹确实存在于User Data目录下，部分场景下Chrome配置文件夹名称可能为Profile 1或其他，需核对实际路径。

• 完整修改后的代码示例：

  from selenium import webdriver
  from selenium.webdriver.chrome.service import Service
  from webdriver_manager.chrome import ChromeDriverManager
  import time
  
  options = webdriver.ChromeOptions()
  # 使用原始字符串避免转义
  options.add_argument(r"--user-data-dir=C:\Users\SIM\AppData\Local\Google\Chrome\User Data")
  options.add_argument("--profile-directory=Profile 6")
  # 屏蔽初始化弹窗
  options.add_argument("--no-first-run")
  options.add_argument("--no-default-browser-check")
  # 启用远程调试端口（可选）
  options.add_argument("--remote-debugging-port=9222")
  
  driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
  time.sleep(3)
