cannot connect to chrome at 127.0.0.1:9222

window10系统，先cmd打开chrome，

chrome --remote-debugging-port=9222
执行脚本

from selenium import webdriver

from selenium.webdriver.chrome.options import Options

from selenium.webdriver.common.by import By

def test_adduser():

    options=Options()

    options.add_experimental_option('debuggerAddress', '127.0.0.1:9222')

    driver=webdriver.Chrome(options=options)

    driver.implicitly_wait(5)

    driver.find_element(By.CSS_SELECTOR,'.js_service_list a:nth-child(1) .index_service_cnt_item_title').click()

报错

>       raise exception_class(message, screen, stacktrace)

E       selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:9222

E       from chrome not reachable

..\venv\lib\site-packages\selenium\webdriver\remote\errorhandler.py:242: WebDriverException

发现打开调试浏览器一段时间后，就会连不上，这是需要关闭浏览器，重新执行chrome --remote-debugging-port=9222
再不行，重启电脑，问题解决
