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

尝试了大量的谷歌搜索，但没有任何帮助。下面是我的代码：

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)

这不是要处理的代码，但我很困惑我在这里遗漏了什么。也请建议一些好的在线资源学习Python Selenium。我打开的chrome如下所示：

Answer 1

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()向现有代码添加参数--no-sandbox，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()
