我试图用不同的帐户访问一些网站，并避免每次我计划为每个网站创建用户配置文件时都登录。我在Ubuntu服务器上托管我的Python应用程序，所以我必须无头运行它，而且我还需要移动仿真。以下是我正在尝试做的一个示例：

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--headless")
options.add_experimental_option("mobileEmulation", {"deviceName": "Pixel 2"})
options.add_argument("user-data-dir=account-data/account_3")
chromedriver = "./webdrivers/chrome"
driver = webdriver.Chrome(executable_path=chromedriver, options=options)

print("START SEARCH")

# Google is an example, but nothing works

driver.get("https://www.google.com")
print("FINISHED")

我看到了START SEARCH，但从未看到FINISHED。然而，当我注解user-data-dir选项时，一切都运行得很完美。奇怪的是，这发生在Ubuntu 20 LTS服务器上，但在我的Mac上没有问题。

在试图获得这个问题的版本时，突然出现了一个不起作用的版本，它给了我这样的信息：

Traceback (most recent call last):
  File "seleniumtest.py", line 12, in <module>
    driver = webdriver.Chrome(executable_path=chromedriver, options=options)
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 81, in __init__
    desired_capabilities=desired_capabilities)
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist
  (Driver info: chromedriver=2.41.578700 (2f1ed5f9343c13f73144538f15c00b370eda6706),platform=Linux 5.4.0-1009-kvm x86_64)

在收到这个错误之前，我唯一真正做过的事情就是删除所有的/tmp/.org.chromium.Chromium.*文件，但这些文件应该只是临时文件，当我没有指定user-data-dir标志时，应该一直创建新的文件。

原来问题是我没有在user-data-dirlag中放入一个绝对路径。

from selenium import webdriver
import os

options = webdriver.ChromeOptions()
path = os.path.abspath("account-data/account_3")
options.add_argument("user-data-dir=" + path)

# other options...

chromedriver = "./webdrivers/chrome"
driver = webdriver.Chrome(executable_path=chromedriver, options=options)

# do stuff...

driver.close()

I don't see any major issue in your code block.

However**chromedriver=2.41.578700**is pretty old and ancient.

Solution

Ensure that:

Selenium is upgraded to current levels Version 3.141.59.
ChromeDriver is updated to current ChromeDriver v83.0 level.
Chrome is updated to current Chrome Version 83.0 level. (as per ChromeDriver v83.0 release notes)
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your @Test asnon-rootuser.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

与其尝试所有代码，不如先下载chromeDriver并安装它。然后将这条路径放入下面的行中。

请记住，当您执行下面的脚本时，将打开一个新的Chrome窗口，但不会关闭它。

from selenium import webdriver

driver = webdriver.Chrome(executable_path=r'C:\Users\sonal\.wdm\drivers\chromedriver\80.0.3987.106\win32\chromedriver.exe')
driver.get("https://www.google.com")

对于Mac用户(M1、M2)核心-

使用seleniarm/standalone-chromium而不是selenium/standalone-chrome
