当我运行 selenium 脚本时出现错误 Value Error: Timeout value connect was <object object at 0x000002A40BE37F80>

Question

我是硒的新手，编写了以下代码来打开亚马逊网站。但是当我运行时，我收到了下面粘贴的错误。

from selenium import webdriver
driver = webdriver.Chrome(executable_path="C:\\Users\\HP\\Desktop\\webdriver\\chromedriver.exe")
driver.get("https://www.amazon.in/")

错误信息：

我检查了是否为上述查询提供了任何说明，但在 stackoverflow 中不可用。

预期结果：脚本应在 Chrome 浏览器中打开亚马逊网站。

Answer 1

得到相同的

日志：ValueError：超时值连接为 <object object at 0x0000017E1D824540>，但它必须是 int、float 或 None。

解决方案

我确认 pip installselenium==4.9.0可能是解决此问题的方法。所以 urllib3 自 4.9.1 以来的更新导致了这个（作为主要原因）

Answer 2

我今天也遇到了同样的问题。更新了 python 和 selenium 并创建了一个新项目。

在与人工智能聊天后，这段代码对我有用。

driver = webdriver.Chrome(service=webdriver.chrome.service.Service(executable_path=<Your Webdriver Path>))

如果您使用的Options是：

driver = webdriver.Chrome(service=webdriver.chrome.service.Service(executable_path=<Your Webdriver Path>), options=chrome_options)

之后，您可能会遇到其他错误，解决方案可以在意外关键字参数“service”错误和“WebDriver”对象没有属性“find_element_by_name”中找到
