从Webpack 1升级到4 ...缩小问题

Question

所以我终于有时间将使用webpack 1（1.13.0）的grunt任务升级到最新的webpack 4（在这个答案的时候：4.30.1）。

在装载机上出现大量错误之后，让所有工作完成，除了引发错误的缩小:(

我注意到Webpack 1输出.js文件为

var MyLibrary =
/******/ (function(modules)  // webpackBootstrap
/******/    // The module cache
/******/    var installedModules = ;
/******/
/******/    // The require function
/******/    function __webpack_require__(moduleId) 
/******/
/******/        // Check if module is in cache
/******/        if(installedModules[moduleId])
/******/            return installedModules[moduleId].exports;
...

但是使用Webpack 4输出是“压缩的”

var MyLibrary=function(e)var n=;function t(a)if(n[a])return n[a].exports;var o=n[a]=i:a,l:!1,exports:;return e[a].call(o.exports,o,o.exports,t),o.l=!0,o.exportsreturn t.m=e,t.c=n,t.d=function(e,n,a)t.o(e,n)||Object.defineProperty(e,n,enumerable:!0,get:a),t.r=function(e)...

并使用与Webpack 1完全相同的源代码

> grunt run --client=mylibrary

Done.

使用Webpack 4我在尝试缩小文件时收到错误

> grunt run --client=mylibrary

在两个版本中，grunt-contrib-uglify插件的设置方式相同

grunt.initConfig(
    uglify: 
        options: 
            sourceMap: false
        ,
        default: 
            files: 
                'dist/mylibrary/mylibrary.min.js': ['dist/mylibrary/mylibrary.js']
            
        
    ,
    ...
);

插件中唯一的变化是现在它是“4.0.1”而之前我使用的是“1.0.2”......但即使改回来，它也会抛出完全相同的错误...所以我认为它是原始文件。 ..

有没有办法像以前一样输出.js文件？
