我是一个新手 selenium 只是想学习。当尝试打开Chrome浏览器通过ChromeDriver我得到了以下错误:

Traceback (most recent call last):
  File "selenium_practise1_chrome.py", line 5, in <module>
    driver = webdriver.Chrome()

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

字符串
尝试了很多谷歌搜索,但没有帮助。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)


这不是一个代码处理,但我很困惑我错过了什么在这里.也请建议一些好的在线资源来学习Python Selenium.我的Chrome打开看起来像下面:

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)

字符串
.表示 ChromeDriver 无法启动/生成新的 WebBrowser,即 Chrome Browser 会话。

溶液

将参数**--no-sandbox**到ChromeOptions()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()

其他注意事项

  • Selenium 升级到当前级别Version 3.14.0
  • ChromeDriver 升级到当前ChromeDriver v2.41级别。
  • Chrome 版本保持在 Chrome v66-68 级别之间。(as per ChromeDriver v2.41 release notes
    • 通过 IDE 清理 * 您的 * 项目工作区 *,并仅使用所需的依赖项 * 重建 * 您的项目。
  • 执行您的 @Test
  • 始终在tearDown(){}方法中调用driver.quit(),以优雅地关闭和销毁 WebDriverWeb Client 示例。
