Question

由于某种原因，我无法弄清楚为什么使用Webpack在生产模式下构建网站失败。当我注释该文件内部的所有内容时，我都有一个文件“ default.js”。

此错误是什么意思？这非常令人困惑，我无法调试。

谢谢！

我的JS文件：

(() => {
    // Do not remove this console log. It serves as a reminder to build in production mode.
    // Building in production mode removes all console, alert and debug statements.
    // NM.
    console.log(

    );

    // Add class top HTML tag if a mobile device is detected.
    const primaryHTML = document.querySelector('html');
