WebDriverException：消息：未知错误：Chrome 无法启动：通过 WebDriverManager 使用 Selenium ChromeDriver 和 Chrome 异常退出

Question

我正在运行这个脚本：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
service = Service(executable_path=ChromeDriverManager().install())
driver = webdriver.Chrome(service=service)
from selenium.webdriver.common.by import By

chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')

driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options)

driver.get('http://192.168.15.1/me_configuracao_avancada.asp',)
user = driver.find_element(By.ID, "txtUser")
user.send_keys("support")
pass_ = driver.find_element(By.ID, "txtPass")
pass_.send_keys("password")
btnLogin = driver.find_element(By.ID, "btnLogin")
btnLogin.click()
driver.get('http://192.168.15.1/reboot.asp',)
reboot = driver.find_element(By.ID, "btnReboot")
reboot.click()
alert = driver.switch_to.alert
alert.accept()
print("Modem Reiniciado!")

我正在使用 Google Chrome 103.0.5060.134、ChromeDriver 103.0.5060.134 和 Selenium 版本 4.3.0。 但是当我运行脚本时，会出现以下错误消息：

几周前脚本运行没有任何问题，但现在它给出了这个错误。 我该如何纠正？

Answer 1

您需要注意以下几点：

• 您只需要一次webdriver.Chrome() 。 如果您不需要 arguments 通过Options()保留：

   driver = webdriver.Chrome(service=service)

  并删除：

   driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options)

  或相反亦然。

• 如果您使用add_argument('--headless')作为非 root 用户执行，通常您甚至可能不需要以下 arguments：

  • add_argument('--no-sandbox')
  • add_argument('--disable-dev-shm-usage')

• 您可以尝试使用以下方法启动新的浏览上下文，即google-chrome-headless ：

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

• 您的有效代码块将是：

   from selenium import webdriver from selenium.webdriver.chrome.options import Options from selenium.webdriver.chrome.service import Service from webdriver_manager.chrome import ChromeDriverManager chrome_options = Options() chrome_options.add_argument('--headless') # optional chrome_options.add_argument('--no-sandbox') # optional chrome_options.add_argument('--disable-dev-shm-usage') driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options) driver.get('http://192.168.15.1/me_configuracao_avancada.asp')

注意：在开始执行测试之前，请确保您已在系统中安装了webdriver-manager和Chrome浏览器。
