Selenium 自动化 Chrome 浏览器打开和关闭并显示错误消息

Question

美好的一天。 在 Stackoverflow 中搜索了大量帖子后，我尝试使用 selenium 和 python 编程来编写和实现自动化。 我尝试了如下的第一个代码，但出现错误。 我的浏览器打开和关闭速度非常快。 它在 output 中引发错误。

代码：-

import time
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

s=Service(ChromeDriverManager().install())
chrome_driver = webdriver.Chrome(service=s)

browser = webdriver.Chrome("/home/halovivek/Documents/Automation/selenium_driver/")
browser.implicitly_wait(5)
browser.get("https://www.google.com")
#browser.get("https://kite.zerodha.com/")
browser.implicitly_wait(5)

错误：-

请帮我

我不明白为什么这条线来了

browser = webdriver.Chrome("/home/halovivek/Documents/Automation/selenium_driver/")

在您已经正确创建了 webdriver 实例之后

s=Service(ChromeDriverManager().install())
chrome_driver = webdriver.Chrome(service=s)

?
看起来您的代码应如下所示：

import time
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

s=Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s)

driver.implicitly_wait(5)
driver.get("https://www.google.com")

UPD
要使您的浏览器保持打开状态，请添加"detach", True选项，如下所示：

import time
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_experimental_option("detach", True)

s=Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s, chrome_options=chrome_options)

driver.implicitly_wait(5)
driver.get("https://www.google.com")
