问题描述

我的 Chrome 浏览器已更新到版本 78，当我尝试执行任何自动化代码时，它会显示错误

My Chrome browser is updated to version 78 and when I tried to execute any code of automation, it shows the error

Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

我该如何解决?

...暗示 ChromeDriver 无法启动/生成新的 WebBrowser 即 Chrome 浏览器 会话.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

第一条日志消息:

Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
