未知错误:会话因未知错误导致页面崩溃而被删除:无法确定 ChromeDriver Selenium 崩溃的选项卡的加载状态 [英] unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed with ChromeDriver Selenium
问题描述
我使用的是使用 Python 和 Selenium 的 InstaPy.我根据 Cron 启动脚本，但它不时崩溃.所以它真的很不规则，有时它运行得很好.我也已经在 GitHub Repo 上发帖了，但没有得到答案，所以我现在在这里问是否有人知道为什么.
I'm using InstaPy which use Python and Selenium. I start the script per Cron and from time to time it crashes. So it'r really irregular, sometimes it runs well through. I'v posted on GitHub Repo as well already but didn't get an answer there, so i'm asking here now if someone has an idea why.
这是一个数字海洋 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.以下是错误消息:
It's a digital ocean ubuntu server and i'm using it on headless mode. The driver version are visible on the log. here are error messages:

推荐答案
虽然你看到的错误是:
Error occurred while deleting cookies from web browser!
b'Message: invalid session id
(Driver info: chromedriver=2.44.609551 (5d576e9a44fe4c5b6a07e568f1ebc753f1214634),platform=Linux 4.15.0-42-generic x86_64)

主要的例外是:
selenium.common.exceptions.WebDriverException: Message: unknown error: session deleted because of page crash
from unknown error: cannot determine loading status
from tab crashed
您的代码试验会为我们提供一些错误的线索.
Your code trials would have given us some clues what going wrong.
这个问题有多种解决方案.但是，根据 UnknownError:会话因标签页崩溃而被删除 这个问题可以可通过以下任一解决方案解决:
There are diverse solution to this issue. However as per UnknownError: session deleted because of page crash from tab crashed this issue can be solved by either of the following solutions:
添加以下
chrome_options:
chrome_options.add_argument('--no-sandbox')
Chrome 在某些页面上的 Docker 容器中似乎由于 /dev/shm 太小而崩溃.因此，您可能需要修复较小的 /dev/shm 大小.
Chrome seem to crash in Docker containers on certain pages due to too small /dev/shm. So you may have to fix the small /dev/shm size.
示例:
sudo mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=512M tmpfs /dev/shm
如果你使用 -v/dev/shm:/dev/shm 选项来共享 host /dev/shm 也可以使用代码>
It also works if you use -v /dev/shm:/dev/shm option to share host /dev/shm
另一种使其工作的方法是将 chrome_options 添加为 --disable-dev-shm-usage.这将强制 Chrome 改用 /tmp 目录.这可能会减慢执行速度，因为将使用磁盘而不是内存.
Another way to make it work would be to add the chrome_options as --disable-dev-shm-usage. This will force Chrome to use the /tmp directory instead. This may slow down the execution though since disk will be used instead of memory.
chrome_options.add_argument('--disable-dev-shm-usage')
来自标签页崩溃是Chromium 团队的 WIP(工作进行中)，现在与 Linux 相关尝试始终将/dev/shm 用于不可执行的内存.以下是参考资料:
from tab crashed was WIP(Work In Progress) with the Chromium Team for quite some time now which relates to Linux attempting to always use /dev/shm for non-executable memory. Here are the references :
- Linux:Chrome/Chromium SIGBUS/啊，快！在小/dev/shm 上
- 当/dev/shm 太小时 Chrome 崩溃/无法加载, 并且位置不能被覆盖
- 根据 Comment61#Issue 736452 修复似乎已经登陆 Chrome v65.0.3299.6
- Linux: Chrome/Chromium SIGBUS/Aw, Snap! on small /dev/shm
- Chrome crashes/fails to load when /dev/shm is too small, and location can't be overridden
- As per Comment61#Issue 736452 the fix seems to be have landed with Chrome v65.0.3299.6
