从渲染器接收消息超时：59,996 使用 Selenium 和 Python

Question

我的脚本有问题。 大约 10 次后，我运行以下命令出现此错误：

Timed out receiving message from renderer: 59,996

我作为ubuntu操作系统使用

• selenium 版本是 3.141.0
• chrome 版本 = 88.0.4324.150
• chromewebdriver = 88.0.4324.96 for linux 64

我该如何解决？

我不明白这个错误可能是什么

Answer 1

此错误消息...

Timed out receiving message from renderer: 59,996

...暗示ChromeDriver 无法与 Browsing Context 即 Chrome 浏览器 会话进行通信。

最可能的原因是你为ChromeDriver配置了太多不必要的参数。

解决方案

去掉不必要的参数，重新测试如下：
