网页包节点。js API和ES6

我已经在ES6中创建了节点API网页包编译器。没有es6,一切都很好。但如果我使用es6,我会得到:

[13:29:41] TypeError: Cannot read property 'concat' of undefined

Process finished with exit code 1

这是我的代码:

import {Compiler} from 'webpack';
const config = require("./config/webpack.config");

class WebpackCompiler {
    constructor(context) {
        this.config = config;
        this.compilerOptions = {};
        this.compiler = new Compiler(context);
    }

    start() {
        this.compiler.options = Object.assign({}, this.config, this.compilerOptions);
        this.compiler.run().then((stats) => this._handleStats(stats)).catch((err) => this._handleErrors(err));
    }

    setOutput(output) {
        this.compilerOptions.output = output;
    }

    setEntries(entires) {
        this.compilerOptions.entry = entires;
    }

    _handleStats(stats) {
        const statsErrors = stats.toJson();

        if (stats.hasErrors()) {
            console.error(statsErrors.errors.toString({
                chunks: false,
                colors: true
            }));
        }

        if (stats.hasWarnings()) {
            console.warn(statsErrors.warnings.toString({
                chunks: false,
                colors: true
            }));
        }
    }

    _handleErrors(err) {
        if (err) {
            console.error(err.stack || err);
            if (err.details) {
                console.error(err.details);
            }
            return;
        }
    }
}

export const CompilerFactory = {
    create: function (context) {
        return new WebpackCompiler(context);
    }
}

在这之后,类似这样的事情:

 var compiler = CompilerFactory.create(WEBPACK_CONTEXT);
    compiler.setEntries({bundle: "./js/main.js"});
    compiler.setOutput("./js/compiled");
    compiler.start();

和简单的网页包配置:

const path = require('path');
const sourcePath = path.resolve("MY_PATH_TO_ROOT");

const mode = process.env.NODE_ENV === 'production' || "development";

module.exports = {
    mode: mode,
    node: {
        __dirname: true
    },
    watchOptions: {
        poll: true
    },
    devtool: "eval",
    entry: {},
    output: {
        filename: '[name].js'
    },
    module: {
        rules: [
            {
                test: /\.(js)$/,
                exclude: /node_modules/,
                use: [
                    {
                        loader: 'babel-loader',
                        options: {
                            sourceMaps: true
                        }
                    }
                ]
            }
        ]
    },

    externals: {
        "jquery": "jQuery"
    },

    resolve: {
        modules: [
            path.resolve(sourcePath, 'node_modules')
        ]
    }
};

问题是在调用方法之后 Run() .在NormalModuleFactory中。js,问题在这一行:

this.ruleSet = new RuleSet(options.defaultRules.concat(options.rules));

正如我所说,关于使用ES6的网页文档中没有太多信息。你们都知道问题出在哪里吗? 谢谢你抽出时间。
