我正在尝试部署我的第一个有角度的应用程序，但是在执行部署过程中，在命令中间：

node node_modules/webpack/bin/webpack.js --mode=production --env.prod

（又名webpack --mode=production --config webpack.config.js --env.prod）

我收到一个一般性错误，该错误不会为我提供以下信息：

Hash: 7b126cdcbdda85d6b0f304152e501136ec85ed58

主服务器和主客户端都是webpack生成的文件，在我的代码中“窗口”的唯一用法是执行window.history.back()命令，但即使对其进行注释，仍然会出现错误。

有人知道如何解决吗？

我的webpack版本是4.6.0 我的webpack.config.js内容如下：
||
===> 更新 -不必要的webpack.config.js内容与问题本身无关

$ npm install webpack -g
 
$ npm install webpack-cli -g
全局安装webpack

$ npm run dev

var gulp = require('gulp');
var webpack = require('webpack');
var gutil = require('gutil');
var babel = require('babel/register');
var config = require(path.join('../..','webpack.config.es6.js'));

gulp.task('webpack-es6-test',function(done){
   webpack(config).run(onBuild(done));
});

function onBuild(done) {
    return function(err,stats) {
        if (err) {
            gutil.log('Error',err);
            if (done) {
                done();
            }
        } else {
            Object.keys(stats.compilation.assets).forEach(function(key) {
                gutil.log('Webpack: output ',gutil.colors.green(key));
            });
            gutil.log('Webpack: ',gutil.colors.blue('finished ',stats.compilation.name));
            if (done) {
                done();
            }
        }
    }
