使用指定Chrome配置文件启动Selenium时程序崩溃求助

问题重现 #

尝试用Selenium启动带有指定Chrome配置文件的浏览器时出现崩溃，报错提示DevToolsActivePort file doesn't exist，相关代码如下：

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 2")
options.add_argument("--user-data-dir=C://Users//user//AppData//Local//Google//Chrome//User Data")
#options.add_argument('--headless')

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)

time.sleep(3)

控制台错误输出：

解决方案 #

1. 关闭所有Chrome进程 #

打开任务管理器，结束所有chrome.exe和chromedriver.exe进程，避免配置文件被其他实例占用。

2. 修正路径格式 #

Windows路径建议使用原始字符串（前缀r）或单斜杠，避免转义字符引发的问题：

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

3. 添加必要的启动参数 #

添加以下参数解决DevToolsActivePort相关冲突：

options.add_argument("--no-sandbox")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--remote-debugging-port=9222")  # 指定固定调试端口，避免端口占用

4. 验证配置文件路径 #

确认Profile 2文件夹确实存在于User Data目录下，路径名称需完全匹配（注意大小写、空格）。

5. 复制配置文件到独立目录（可选） #

如果原用户数据目录被其他Chrome实例占用，可复制Profile 2到新的独立目录，再修改代码中的路径：

options.add_argument(r"--user-data-dir=C:\Users\user\Documents\MyChromeProfile")
options.add_argument("--profile-directory=Profile 2")

修改后的完整代码 #

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(r"--user-data-dir=C:\Users\user\AppData\Local\Google\Chrome\User Data")
options.add_argument("--profile-directory=Profile 2")
options.add_argument("--no-sandbox")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--remote-debugging-port=9222")

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)

time.sleep(3)
driver.quit()  # 程序结束时主动关闭浏览器进程
