email_input = driver.find_element(By.NAME, "email_or_username")

Question

当我运行我编写的代码时，遇到错误。我正在使用 selenium 4.14.0 和 mozilla 119.0 以及 GeckoDriver-v0.33.0 我写的代码：

from selenium import webdriver
from selenium.webdriver.common.by import By
driver = webdriver.Firefox()
driver.get("https://www.instagram.com/")
email_input = driver.find_element(By.NAME, "email_or_username")
email_input.send_keys("email_address")
password_input = driver.find_element(By.NAME, "password")
password_input.send_keys("password")
driver.quit()

Traceback (most recent call last):
  File "C:/Desktop/h.py", line 9, in <module>
    email_input = driver.find_element(By.NAME, "email_or_username")
  File "C:\AppData\Local\Programs\Python\Python312\Lib\site-packages\selenium\webdriver\remote\webdriver.py", line 738, in find_element
