ChromeDriver认为Chrome浏览器已崩溃，因为它启动的进程/usr/bin/google-chrome已经停止运行。

我正在Ubuntu服务器上运行Jupyter Notebook。我尝试使用ChromeDriver运行以下Selenium代码。但是，我遇到了下面的错误。如果我在Ubuntu终端中运行下面的代码行，它会返回下面的输出。有人知道问题可能是什么吗？我对Ubuntu还不太熟悉。

Ubuntu代码：

which google-chrome

输出：

/usr/bin/google-chrome

Jupyter Notebook 代码：

driver = webdriver.Chrome(executable_path=os.path.abspath("/home/username/chromedriver"), chrome_options=chrome_options)

错误：

更新：

chrome_options.add_argument("no-sandbox")
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--headless")

由于某种原因，在我的代码中添加了以上这些行后，问题得以解决。我在下面的文章中找到了这段代码。

这个错误信息...

WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (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=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Linux 4.15.0-46-generic x86_64)

这意味着ChromeDriver无法启动/生成新的WebBrowser，即Chrome浏览器会话。

您的主要问题在于以下二进制文件版本之间的不兼容性：

支持Chrome v74

  • 也许您正在使用最后一个GAed版本的Chrome浏览器，即chrome=73.x

因此，ChromeDriver v74.0.3729.6和Chrome浏览器v73.x之间存在明显的不匹配。

解决方案

  • 将 ChromeDriver 降级至 ChromeDriver v73.0.3683.68 版本。
  • 保持 Chrome 版本在 Chrome v73 级别。（根据 ChromeDriver v73.0.3683.68 发布说明）
  • 通过你的 IDE 清理你的 项目工作区，并仅使用所需的依赖项重新构建你的项目。
  • 执行你的 @Test。
  • 始终在 tearDown(){} 方法中调用 driver.quit() 以优雅地关闭和销毁 WebDriver 和 Web 客户端实例。
谢谢您回复我。我下载了chromedriver的版本，现在我得到了相同的错误，但是使用新版本的chromedriver。我在原始帖子中添加了一个更新，其中包含错误信息。我还检查了正在运行的google-chrome版本为73.0.3683.103。（我也在更新中包括了它。）这是否意味着我必须获取chrome-driver 73.0.3683.103？ - user3476463
我添加了一些在相关帖子中找到的解决问题的代码。我更新了代码并附上了帖子链接。 - user3476463
@user3476463，我本可以在答案中提供其他建议，但我尝试根据你的问题提供一个规范的答案。很高兴听到你的问题得到了解决。祝你好运。 - undetected Selenium
谢谢你的所有帮助。你能告诉我这三行代码的作用吗？ "chrome_options.add_argument("no-sandbox") chrome_options.add_argument("--disable-extensions") chrome_options.add_argument("--headless")" - user3476463
@user3476463 先生，我已经在我的答案中提供了所有的解释，就像这个问题中链接的那样，以 addArguments("--no-sandbox"); // Bypass OS security model 和 addArguments("--disable-extensions"); // disabling extensions 的形式。如果您需要进一步的帮助，请告诉我。 - undetected Selenium
