Python Selenium By 引发 AttributeError：类型对象“By”没有属性“XPATH”

Question

我对硒有疑问。

def main_test():
    chrome_options = Options()
    prefs = {"download.default_directory": f"{os.getcwd()}/Music"}
    chrome_options.add_argument("user-data-dir=selenium")
    chrome_options.add_experimental_option("prefs", prefs)
    dr = webdriver.Chrome(options=chrome_options, service=Service(ChromeDriverManager().install()))
    dr.get(URL)
    print(f"{selenium.__version__=}")
    dr.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/ul/li[2]/a").click()
    dr.quit()


if __name__ == '__main__':
    main_test()

这是我的代码。我想我正确地遵循了文档。虽然，运行应用程序时我收到此错误：

selenium.__version__='4.6.0'
Traceback (most recent call last):
  File "/Users/andrea/Dev/Python/custom_scripts/ytchannel/main.py", line 142, in <module>
    main_test()
  File "/Users/andrea/Dev/Python/custom_scripts/ytchannel/main.py", line 137, in main_test
    dr.find_element(By.XPATH, "/html/body/div[1]/div[1]/div/div[1]/ul/li[2]/a").click()
AttributeError: type object 'By' has no attribute 'XPATH'

我不知道我做错了什么...... 如果需要，我可以添加所有可能的细节。

编辑： 这是我的进口：

import os

import httpx as web
from selenium import webdriver

from selenium.webdriver.chrome.service import Service
