python - Python selenium 代码不适用于我的电脑上的选项

Question

我在 python (spyder 3.8) 中有一个带有 selenium 的webscraping代码，我需要点击一些 url 中的几个按钮来下载一些文件。我已经在 2 台不同的 pc 上尝试了我的代码，它运行良好，但是当我在我的办公室 pc 上运行它时它没有，我需要能够在那里运行它。问题是，当我在 chromedriver 上添加选项时，代码只是打开浏览器，但它什么也不做，它没有转到 url，过了一段时间它说错误“WebDriverException：未知错误：DevToolsActivePort 文件没有不存在”。如果我在没有任何选项的情况下运行它，它确实可以工作，但我需要包含它们。

我已经检查了 chrome 版本是否与驱动程序兼容，并尝试在没有任何选项的情况下运行代码，它确实有效。此外，如果我直接使用 driver.get 而不是 WebDriverGet，它似乎可以与选项一起使用，但我需要使用 WebDriverWait 来制作更稳定的代码，我真的不知道问题出在哪里:(。谢谢请注意！
