我想这就是你想要的：

# Needed libs
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

#Open the browser
driver = webdriver.Edge()
driver.get("https://www.instagram.com/")

# Wait and click for allow cookies button
allow_cookies_button = date = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, f"//button[text()='Only allow essential cookies']")))
allow_cookies_button.click()
# Wait and click for Sign in button
signup_button = date = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, f"//span[text()='Sign up']")))
signup_button.click()

# This time.sleep is to allow you to see what happened, you can delete it
time.sleep(5)
# Close the browser
driver.close()

为什么你的代码不工作？因为正如你的控制台告诉你的，“find_element_by_xpath”不是驱动程序的有效方法/属性。
自动化/刮削建议：

• 等待您将使用的元素（无论您想写、单击还是其他操作，都要确保该元素在屏幕上）
• 尝试使用可理解的xpath（或任何选择器），您将在将来重用它们。您更了解什么，//span[text()='Sign up']还是//*[@id='mount_0_0_+h']/div/div/div/div[1]/div/div/div/div[1]/section/main/article/div[2]/div[2]/div/p/a/span？好的选择器将在将来保存大量时间
