如何使用Selenium和ChromeDriver解决异常

Question

我正在运行ChromeDriver(v89(&Selenium 4.1在MacOS上，当通过传递ChromeDriverService的实例和以下选项实例化ChromeDriver时，我得到了一个异常：

{
"browserName": "chrome",
"goog:chromeOptions": {
"args": [
"no-sandbox"
],
"debuggerAddress": "127.0.0.1:8080"
}
}

异常详细信息：

同样的代码在Windows上运行良好，所以我敢说它已经过测试。

我想我找到了答案：计划是提前启动一个单独的进程来运行CEF和网站，但这一步失败了，所以没有浏览器可以与之对话。糟糕的是，我应该在这里发帖之前检查一下。
