未捕获的 ReferenceError：Vue Js 中的 webpackJsonp

Question

我突然开始在 Vue Js 中遇到 Uncaught ReferenceError: webpackJsonp。我对 Js 相当陌生，刚刚开始使用 Vue 应用程序。我尝试了 Git 和 stackoverflow 中提到的各种解决方案，但都没有奏效。谁能帮帮我。

为了提供一些背景信息，这个问题突然出现而没有做出太大的改变。代码在之前的状态下工作，但对组件进行任何更改，即使修改 css 也开始导致问题。 根据我对这个问题的了解，它应该由 webpack.prod.conf.js 控制（下面附上我的）。如果需要任何其他信息，请告诉我。

配置中缺少入口点，即您没有通知 webpack 应用程序应该从哪里开始。 这个问题也正在发生，因为您提到了vendor 请参考this link
