1. 示例代码
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('http://124.223.30.31:xxx/forum.php')
driver.find_element('id','ls_username').send_keys('admin')
端口我匿了
这个代码是没有问题的，任意其他代码在当前的环境下都是会出现这个错误的
2. 报错
从下面的报错可以看到在find_element的时候出错了，而这个代码以前是ok的
核心的出错提示selenium.common.exceptions.WebDriverException: Message: unknown error: result.webdriverValue.value list is missing or empty in Runtime.callFunctionOn response
闻所未闻哈~
Traceback (most recent call last):

3. 搜
匹配的结果不多，倒还有
原来是驱动版本的问题
4. 环境
当前环境:
chrome version:119.0.6045.124 (正式版本) （64 位） (cohort: Stable)
chromedriver version: 118.0.5993.70
selenium:4.3.0
更新下驱动https://googlechromelabs.github.io/chrome-for-testing/
下载替换，再次运行搞定
