selenium.common.exceptions.SessionNotCreatedException

Question

我正在尝试运行这个应用程序：https://github.com/flathunters/flathunter

我在一个新的Ubuntu18.04.6LTS安装上安装了这个程序。这个包需要Python。我使用的是pipenv install和pipenv shell，这是安装说明中推荐的。

另外，还需要一个铬网驱动程序.我试图按照https://stackoverflow.com/a/32139981/2311074中的解释，在VPS上安装它，并将它指向/usr/lib/chromium-browser/chromedriver。

我每天开始写剧本长达14个小时。应用程序可以工作几天，然后它将始终使用selenium.common.exceptions.SessionNotCreatedException退出。

如果我直接从https://chromedriver.chromium.org/下载铬驱动程序，同样的问题。

我安装了铬和铬驱动程序v98 .

当我重新安装这台机器时，它会再工作几天，然后在某一天永远失效。

我在这里做错什么了？

会话selenium错误的原因是无法打开selenium浏览器。这是因为每次启动脚本时都会打开selenium浏览器，但是如果脚本停止，chromedriver就不会关闭。过了一段时间，您打开了许多显色驱动器：

并启动一个新的色度驱动器填充失败与“端口已经在使用”。

要修复它，可以在启动脚本之前杀死所有chromedriver。

killall chromedriver
