Question

我正在研究Vue.js项目，并且突然出现错误，而不是控制台上的错误（console.error）是警报（正常的浏览器警报）。

示例。我强迫写(undefined).anyProperty

时出错

Error on alert instead of console

控制台外观：

normal console

我的package.json模块：

我可以在警报中调试，因为对象是[对象对象]，谢谢帮助。

Answer 1

所以我为您做了一些研究，但实际上还没有检验我的假设，因此请带着一点盐...

我的直觉告诉我，在代码中的某处，有一个附加到窗口错误事件的事件处理程序，该事件处理程序警告错误消息并吞下错误。在代码库中搜索addEventHandler('error'，addEventHandler("error"和onerror，然后删除它：-）

Answer 2

我对Vue一无所知，但我建议对此进行调试，是将window.alert函数替换为您自己的包含debugger的函数

let oldWindowAlert = window.alert;
window.alert = function(){ 
  debugger; 
  oldWindowAlert.apply(window, arguments); 
}

然后，当您抓住调试器后，就可以调查调用堆栈（在Chrome中这很容易），以查明发出此警报的函数。

The docs使我相信Node_Notifier是罪魁祸首。很难看到而不看代码，但是也许看到如果删除它会发生什么？

我代码上的错误是警报，而不是console.errors
