問題描述

我正在使用使用 Python 和 Selenium 的 InstaPy.我按 Cron 啟動腳本，但有時它會崩潰.所以它真的很不規(guī)則，有時它運行得很好.我也已經(jīng)在 GitHub Repo 上發(fā)布過，但那里沒有得到答案，所以我現(xiàn)在在這里問是否有人知道原因.

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.

這是一個數(shù)字海洋 ubuntu 服務(wù)器，我在無頭模式下使用它.驅(qū)動程序版本在日志中可見.以下是錯誤消息:

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:

推薦答案

雖然你看到的錯誤是:

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

您的代碼試驗會給我們一些線索，說明出了什么問題.

Your code trials would have given us some clues what going wrong.

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