我已经遇到这个问题两次：Selenium WebDriver更新后需要Chrome的新版本，但Chrome还检测不出新版本。第一次遇到时，Chrome需要大约15天才能赶上。

有没有办法强制更新Chrome，或者让Python使用旧版本的Selenium WebDriver？我在Windows 11上。

我尝试使用下面这段代码降级Selenium WebDriver，但仍然遇到同样的错误。

service = Service(ChromeDriverManager(driver_version="144").install())
browser = webdriver.Chrome(service=service)

Error:

Message: session not created: cannot connect to chrome at 127.0.0.1:56620
from session not created: This version of ChromeDriver only supports Chrome version 146
Current browser version is 145.0.7632.117; For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#sessionnotcreatedexception

解决方案

自Selenium 4.6起，新增了 Selenium Manager，它会自动为你下载并配置合适的驱动。因此，你不再需要使用DriverManager或指定路径等。

有了内部驱动管理器，它会下载与已安装浏览器匹配的驱动，因此应该能避免你描述的问题。

这就是你需要的全部代码...

from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window()
driver.get('http://www.google.com')
