显示WebDriver没有这个方法啊find_element_by_link_text'

#python 我从网上学了一个秒杀脚本，从网上查了WebDriver提供的8种元素定位方法，但为什么这里显示WebDriver没有这个方法啊find_element_by_link_text'，求告知

from selenium import  webdriver
import datetime
import time

# 连接Chrome浏览器
driver = webdriver.Chrome()

def login(url):
    # 打开淘宝登录页，并进行登录
    driver.get("https://www.taobao.com/")
    time.sleep(3)
    if driver.find_element_by_link_text("亲，请登录"):
        driver.find_element_by_link_text("亲，请登录").click()
        print("请在20秒内完成登录")
        time.sleep(3)
        driver.get(url)
    time.sleep(3)
    now = datetime.datetime.now()
    print('login success:',now.strftime('%Y-%m-%d %H:%M:%S'))


def buy(buytime):
    while True:
        now = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
        # 对比时间 ，时间到的话点击结算
        if now >= buytime:
            try:
                # 立即抢购
                if driver.find_element_by_id("J_LinkBuy"):
                    print("速度点击！！！")
                    driver.find_element_by_id("J_LinkBuy").click()
                    time.sleep(0.09)
                    while now >= buytime:
                        try:
                            print('正在提交订单')
                            if driver.find_element_by_class_name('go-btn'):
                                driver.find_element_by_class_name('go-btn').click()
                        except:
                            time.sleep(0.02)
            except:
                time.sleep(0.08)
        print(now)
        time.sleep(0.05)

if __name__ == "__main__":
    times = input('请输入抢购时间：时间格式：2021-12-29 19:45:00.000000')
    url = input('请输入抢购地址')
    login(url)
    buy(times)

运行结果及报错内容

Traceback (most recent call last):
  File "C:\Users\32739\Desktop\python自动化\shopping_taobao.py", line 48, in 
    login(url)
  File "C:\Users\32739\Desktop\python自动化\shopping_taobao.py", line 12, in login
    if driver.find_element_by_link_text("亲，请登录"):
AttributeError: 'WebDriver' object has no attribute 'find_element_by_link_text'

我想要达到的结果

使整个代码能够正常运行

新版本全都换成这种了：
from selenium.webdriver.common.by import By
• find_element(By.ID,”loginName”)
• find_element(By.NAME,”SubjectName”)
• find_element(By.CLASS_NAME,”u-btn-levred”)
• find_element(By.TAG_NAME,”input”)
• find_element(By.LINK_TEXT,”退出”)
• find_element(By.PARTIAL_LINK_TEXT,”退”)
• find_element(By.XPATH,”.//*[@id=’Title”)
• find_element(By.CSS_SELECTOR,”[type=submit]”)
