Question

从Webpack 1升级到2后出错。配置未更改且之前没有错误。请帮忙！谢谢！

Webpack配置：

const path = require('path');
const root = path.resolve(__dirname);
const webpack = require('webpack');
const merge = require('webpack-merge');
const ArchivePlugin = require('webpack-archive-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');

let config = {
    cache: true,
    devtool: 'cheap-module-source-map',
    entry: {
        polyfills: './src/polyfills.browser.ts',
        vendor: './src/vendor.browser.ts',
        main: './src/main.browser.ts'
    },
    output: {
        path: path.join(__dirname, 'dist/output'),
        filename: '[name].bundle.js',
        sourceMapFilename: '[name].map',
        chunkFilename: '[id].chunk.js'
    },
    resolve: {
        extensions: ['.ts', '.js'],
        alias: {jquery: 'jquery/dist/jquery'}
    },
    devServer: {
        inline: true,
        contentBase: 'src',
        historyApiFallback: true,
        watchOptions: {aggregateTimeout: 300, poll: 1000}
    },
    node: {
        net: 'empty',
        global: true,
        crypto: 'empty',
        module: false,
        Buffer: false,
        clearImmediate: false,
        setImmediate: false
    },
    plugins: [
        new webpack.optimize.CommonsChunkPlugin({
            name: ['main', 'vendor', 'polyfills'],
            minChunks: Infinity
        }),
        new webpack.ProvidePlugin({
            $: "jquery",
            jQuery: "jquery",
            "window.jQuery": "jquery"
        }),
        new webpack.DefinePlugin({
            "require.specified": "require.resolve"
        })
    ],
    module: {
        exprContextCritical: false,
        rules: [{
            test: /\.ts$/,
            loaders: ['awesome-typescript-loader', 'angular2-template-loader']
        }, {
            test: /\.css$/,
            loaders: ['to-string-loader', 'style-loader', 'css-loader']
        }, {
            test: /\.scss$/,
            loaders: ["style-loader", "css-loader", "sass-loader"]
        }, {
            test: /\.json$/,
            loader: 'raw-loader'
        }, {
            test: /\.html$/,
            loader: 'raw-loader'
        }, {
            test: /\.(png|jpg|gif)(\?v=\d+\.\d+\.\d+)?$/,
            loader: 'url-loader?limit=100000'
        }, {
            test: /\.(eot|com|json|ttf|woff|woff2)(\?v=\d+\.\d+\.\d+)?$/,
            loader: "url-loader?limit=10000&mimetype=application/octet-stream"
        }, {
            test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
            loader: 'url-loader?limit=10000&mimetype=image/svg+xml'
        }]
    },
};

if (process.argv[1].indexOf('webpack-dev-server') === -1) {
    module.exports = merge(config, {
        plugins: [
            new CleanWebpackPlugin(['dist']),
            new ArchivePlugin(),
            new webpack.optimize.UglifyJsPlugin({output: {comments: false}})
        ]
    });
} else {
    module.exports = config;
}

这些是控制台中显示的错误。

*****我必须添加这些行来发布这个问题，涉及太多代码*****

Answer 1

我发现了发生了什么。它不是关于webpack，而是关于Angular2的变化

我试图投放this.router.navigate([redirectUrl]);，而redirectUrl是undefined。它导致了错误。

升级到Webpack 2后出错。请求的路径包含索引0处的未定义段
