Мобильная версияСам список содержит несколько тысяч URL-адресов.
Итак, я пытаюсь использовать пул процессов для управления несколькими экземплярами Google Chrome. И мне нужно указать каталог пользователя для доступа к его файлам cookie с помощью аргумента --user-data-dir.
Но я получил сообщение об ошибке:< /p>
Message: session not created
from unknown error: Could not remove old devtools port file. Perhaps the given user-data-dir at C:\Users\ilpla\AppData\Local\Chromium\User Data is still attached to a running Chrome or Chromium process
Есть ли способ открыть несколько экземпляров Google Chrome без возникновения этой ошибки?
Вот код, который я пытаюсь использовать:< /p>
