我的代码中的错误是警报，而不是 console.errors

Question

我正在做 Vue.js 项目，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）。

例子。我强迫这个错误写 (undefined).anyProperty

控制台外观：

我的 package.json 个模块：

    "axios": "^0.18.0",

    "npm": ">= 3.0.0"
  },
  "browserslist": [
    "> 1%",

    "not ie <= 8"
  ]

我可以在警报中调试，因为对象是 [Object object]，感谢您的帮助。

Answer 1

The docs 让我相信 Node_Notifier 是罪魁祸首。没有看到您的代码很难说，但也许可以看到如果删除它会发生什么？

Answer 2

所以我为您做了一些研究，但还没有真正检验我的假设，所以请对此持保留态度...

我的直觉告诉我，在代码的某处有一个事件处理程序附加到 window 错误事件，它会提醒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 3

我对 Vue 一无所知，但我的调试建议是将 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，一旦捕获到调试器，您就可以调查调用堆栈（在 Chrome 中这很容易）以追踪发出此警报的函数。

我的代码中的错误是警报，而不是 console.errors

Errors on my code are alerts, instead of console.errors
