未知错误：会话因页面崩溃而从未知错误中删除：无法通过ChromeDriver Selenium崩溃的选项卡确定加载状态

我正在使用使用Python和Selenium的InstaPy。我每个Cron都会启动脚本，并且有时会崩溃。所以它确实是不规则的，有时运行得很好。我也已经在GitHub
Repo上发布了消息，但是在那儿没有得到答案，所以我现在在这里问是否有人知道为什么。

这是一台数字海洋ubuntu服务器，我在无头模式下使用它。驱动程序版本在日志中可见。这是错误消息：

知道原因可能是什么以及如何解决？

答案1

虽然您看到的错误为：

Error occurred while deleting cookies from web browser!b''Message: invalid session id\n  (Driver info: chromedriver=2.44.609551 (5d576e9a44fe4c5b6a07e568f1ebc753f1214634),platform=Linux 4.15.0-42-generic x86_64)\n''

主要的例外是：

selenium.common.exceptions.WebDriverException: Message: unknown error: session deleted because of page crashfrom unknown error: cannot determine loading statusfrom tab crashed

您的代码试用会为我们提供一些出了什么问题的线索。

解

有多种解决此问题的方法。但是，按照UnknownError：由于标签页崩溃导致会话删除，会话可以通过以下解决方案之一解决：

• 添加以下内容chrome_options：

  chrome_options.add_argument(''--no-sandbox'')

• 由于太小，Chrome似乎在某些页面的Docker容器中崩溃/dev/shm。因此，您可能必须修复较小的/dev/shm尺寸。

• 一个例子：

  sudo mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=512M tmpfs /dev/shm

• 如果您使用-v /dev/shm:/dev/shm选项共享 主机， 它也可以工作 __/dev/shm

• 使它起作用的另一种方法是将chrome_optionsas 添加 --disable-dev-shm-usage 。这将迫使Chrome使用该/tmp目录。尽管这会减慢执行速度，因为将使用磁盘而不是内存。

  chrome_options.add_argument(''--disable-dev-shm-usage'')

从标签页崩溃

从标签崩溃的 是 Chromium团队 进行WIP（ 工作进行中 ）了相当长时间了，这与 Linux试图始终使用/ dev /
shm作为不可执行内存有关 。以下是参考资料：

• Linux：Chrome / Chromium SIGBUS / Aw，Snap！在小型/ dev / shm上
• 当/ dev / shm太小且无法覆盖位置时，Chrome崩溃/无法加载
• 根据Comment61＃Issue 736452，此修复程序似乎已随 Chrome v65.0.3299.6 一起 发布

Chrome-org.openqa.selenium.WebDriverException：未知错误：无法在driver.manage（）window（）maximize（）;处获得自动化扩展

driver.manage().window().maximize();

org.openqa.selenium.WebDriverException: unknown error: cannot get automation extension
from unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html
(Session info: chrome=57.0.2987.110)

Command duration or timeout: 10.05 seconds

1. Updated Chrome driver to latest i.e 2.28 for my Chrome version 
   57.0.2987.110 (64-bit)
2. uninstalled and re-installed Chrome
3. did a project build up in Eclipse even created a new workspace

    ChromeOptions options = new ChromeOptions();
    options.addArguments("start-maximized");
    driver = new ChromeDriver();

Chrome-org.openqa.selenium.WebDriverException：未知错误：无法在driver.manage（）。window（）。maximize（）;处获得自动化扩展

我被Chrome浏览器抛出了一种非常不寻常的错误

当我尝试使用以下代码行最大化chrome时

driver.manage().window().maximize();

我低于错误

org.openqa.selenium.WebDriverException: unknown error: cannot get automation extensionfrom unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html(Session info: chrome=57.0.2987.110)(Driver info: chromedriver=2.27.440174 (e97a722caafc2d3a8b807ee115bfb307f7d2cfd9),platform=Windows NT 6.3.9600 x86_64) (WARNING: The server did not provide any stacktrace information)Command duration or timeout: 10.05 seconds

通过本示例，我做了以下事情

1. Updated Chrome driver to latest i.e 2.28 for my Chrome version    57.0.2987.110 (64-bit)2. uninstalled and re-installed Chrome3. did a project build up in Eclipse even created a new workspace

但是没有帮助，所以我用了

    ChromeOptions options = new ChromeOptions();    options.addArguments("start-maximized");    driver = new ChromeDriver();

它可以正常工作，Chrome驱动程序没有显示任何错误， 但是 每当我执行一段代码（例如填写表格或单击某个按钮）后，一段时间后仍然会抛出上述错误。

答案1

通常，您看到的原因 WebDriverException: unknown error: cannot get automationextension 可能很多。看到此异常的两种最常见的情况是：

1. 二进制版本 chromedriver 和 Chrome Browser 二进制版本之间不匹配。 解决方案 ：按照 ChromeDriver Release Notes
2. 利用driver.manage().window().maximize();最大化Chrome Browser。 解决方案 ： ChromeOptions.addArguments("start-maximized"); 用于最大化Chrome Browser。

根据您的问题，异常似乎来自上述情况之一。

试用以下步骤：

1. 杀死chromedriverWindows任务管理器中运行的所有实例。
2. 使用CCleaner工具清除所有OS杂务。
3. 在Eclipse中清理所有项目。
4. 重启系统一次。
5. 提供以下选项以启动您的Chrome浏览器：

   ChromeOptions options = new ChromeOptions();

   options.addArguments(“test-type”);
   options.addArguments(“start-maximized”);
   options.addArguments(“disable-infobars”);
   options.addArguments(“–disable-extensions”);
   driver = new ChromeDriver(options);

您的程序应与最新的chrome驱动程序2.28和Chrome版本57.0.2987.110（64位）一起使用。让我知道这是否对您有帮助。
