python - Selenium 无法打开指定的 URL 并显示数据 :,

Question

我正在尝试在 Chrome 中使用 selenium 打开 URL。我有 chromedriver 可用。

以下是我要执行的代码。

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--disable-infobars")

driver = webdriver.Chrome(executable_path="./chromedriver", chrome_options=chrome_options)
driver.get("https://google.com")

浏览器已成功打开，但未打开指定的 URL。浏览器中的 URL 为 data:,。

任何帮助将不胜感激。请!

请参阅附图。

注意:Selenium 版本:3.14.0

关闭 chrome 选项卡时出现以下错误。

File "test.py", line 6, in <module>
    driver = webdriver.Chrome(executable_path="./chromedriver", chrome_options=chrome_options)

  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver=2.42.591071 (0b695ff80972cc1a65a5cd643186d2ae582cd4ac),platform=Linux 4.10.0-37-generic x86_64)

Answer 1

此错误消息...

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited normally
  (chrome not reachable)
  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

...表示 ChromeDriver 实例无法启动 Chrome 浏览器 进程。

您的主要问题是 google-chrome 不再出现在预期的默认位置 /usr/bin/

根据 ChromeDriver - Requirements服务器希望您将 Chrome 安装在每个系统的默认位置:

¹ 对于 Linux 系统，ChromeDriver 期望/usr/bin/google-chrome 是实际 Chrome 二进制文件的符号链接(symbolic link)。您还可以覆盖 Chrome 二进制文件位置，如下所示:

• 基于 Windows 操作系统的示例:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.add_argument("start-maximized")
  options.binary_location("C:\\path\\to\\chrome.exe")
  driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
  driver.get('http://google.com/')
  

其他注意事项

• 将ChromeDriver升级到当前的ChromeDriver v2.42级别。
• 将 Chrome 版本保持在 Chrome v68-70 级别之间。 (as per ChromeDriver v2.42 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项目。
• 如果您的基本网络客户端版本太旧，请通过 Revo Uninstaller 卸载它并安装最新的 GA 和已发布版本的Web 客户端。
• 执行您的@Test。
