我得到 AttributeError: 'WebDriver' object 沒有屬性 'find_element_by_class_name'

Question

（下面的代碼不是我的）我一直在努力讓這個 ixl 數學機器人工作，但每次我運行它我都會得到

AttributeError: 'WebDriver' object 沒有屬性 'find_element_by_class_name'

我正在使用 selenium 4.3 和最新的 python 版本，如果沒有人可以提供幫助，那么至少解釋一下這個錯誤的含義以及我如何解決它，我們將不勝感激， https://github.com/debaet/IXLMultiBot?adlt=strict&toWww =1&redig=1D778E48B58B4E39B6F7082C77F7F797這是原來的GitHub帖子（不是我的）

我是 python 的新手，所以我只嘗試了一些基本的東西，比如重述 PATH 或雙“\”

它應該要求用戶名密碼等級和課程鏈接有效但在 selenium chrome windows 打開后它得到：

AttributeError: 'WebDriver' object 沒有屬性 'find_element_by_class_name'

在當前的 Selenium 版本中，所有find_element_by_*和find_elements_by_*方法都已棄用。 你需要使用driver.find_element(By.CLASS_NAME, " ") , driver.find_element(By.XPATH, " ")等方法。
