python - 无法启动 Selenium，遇到 DeprecationWarning 和 WebDriverException 错误

Question

今天突然，我的项目中无法启动Selenium。错误信息如下:

main.py:11: DeprecationWarning: executable_path has been deprecated, please pass in a Service object
  driver = webdriver.Chrome(options=options,executable_path='drivers/chromedriver-linux64/chromedriver')
Traceback (most recent call last):

我的Dockerfile设置如下:

需求.txt

selenium==4.15.1

而且，我创建了一个简单的 main.py 来启动 Selenium。

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.headless = True
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')

driver = webdriver.Chrome(options=options)

driver.get('https://www.google.com')
print(driver.title) 

driver.quit()

我做了什么

我从此链接下载了119和120版本的驱动程序，将它们设置在executable_path中，并执行它，但返回了相同的错误。 https://googlechromelabs.github.io/chrome-for-testing/#stable

请帮助我!

环境

MacOS 13.6 苹果M2 Docker桌面版4.21.1

在 Selenium 4 中，executable_path 已弃用，您必须将 Service() 类的实例与 ChromeDriverManager().install() 结合使用

• Deprecate all but Options and Service arguments in driver instantiation. (#9125,#9128)

https://github.com/SeleniumHQ/selenium/blob/d6acda7c0254f9681574bf4078ff2001705bf940/py/CHANGES#L101

你可以尝试:

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

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
driver.get("https://www.your_website_.com")

---

编辑:在查看您的示例后，我认为您可以尝试:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
service = Service(r"C:\chromedriver.exe")   # your path to chromedriver executable file
options = webdriver.ChromeOptions()
driver = webdriver.Chrome(service=service, options=options)

driver = webdriver.Chrome(options=options)

driver.get('https://www.google.com')
print(driver.title) 

driver.quit()
