我是硒的新手,只是想学习。尝试通过ChromeDriver打开Chrome浏览器时出现以下错误:
Traceback (most recent call last):

selenium.common.exceptions.WebDriverException: Message: unknown error: unable to discover open pages

尝试了很多谷歌搜索,但没有任何帮助。以下是我的代码:
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.common.keys import Keys
driver = webdriver.Chrome()
driver.get('http://www.python.org')
print(driver.title)
这不是一个需要处理的代码,但我很困惑我在这里缺少什么。另外,请提供一些很好的在线资源来学习Python Selenium。我打开的Chrome看起来如下:
此错误消息...
selenium.common.exceptions.WebDriverException: Message: unknown error: unable to discover open pages
(Driver info: chromedriver=2.40.565498 (ea082db3280dd6843ebfb08a625e3eb905c4f5ab),platform=a lotows NT 6.1.7601 SP1 x86_64)
...暗示ChromeDriver无法启动/生成新的WebBrowser,即Chrome浏览器会话。
通过ChromeOptions()
将参数--no-sandbox添加到现有代码中,如下所示:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('--no-sandbox') # Bypass OS security model
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://www.python.org')
print(driver.title)
driver.quit()
@Test
。driver.quit()
方法中调用tearDown(){}
以正常关闭和销毁WebDriver和Web Client实例。
