为什么用selenium爬网页出现这种异常提示？

Question

这几天想用selenium爬网页信息，简单写了一个但是总报错，找不到问题原因，各位帮我看看呗,大家可以直接执行我下面的代码，看看报错信息。

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
import csv
import time
#selenium优化选项部分
fox_options = Options()
fox_options.add_argument('--headless')
fox_options.add_argument('--disable-gpu')
fox_options.add_argument('blink-settings=imagesEnabled=false')
fox_options.add_argument('log-level=3')
# 如果firefox没有安装在默认位置，就要手动指定位置
location = 'C:/Firefox/firefox.exe'
driver = webdriver.Firefox(options=fox_options,firefox_binary=location)

# 添加newline可以避免一行之后的空格,这样需要在python3环境下运行
csvfile = open(r'G:\che168\R0610.csv', 'w', newline='', encoding='gb18030')
# 指定逗号作为分隔符，并且指定quote方式为引用。这意味着读的时候都认为内容是被默认引用符(")包围的
writer = csv.writer(csvfile, delimiter=',', quoting=csv.QUOTE_ALL)
keys = ['商家编号','车辆编号','车型','车龄','表显里程','售价','新车价格','上牌时间','折旧率','平均每年贬值','变速箱','排放标准', '排量','过户次数','发布日期','过户次数','所在地','发布日期','发动机','颜色','燃油标号', '驱动方式', '公司名称', '公司地址']
writer.writerow(keys)

Answer 1

可以设置一等待时间，等页面加载完成后再解析
