我的问题是，无论我做什么，我都会得到一个 404，wepack_hmr而且我一生都无法弄清楚为什么它不可用。

完整的 Webpack 配置

var url = 'http://localhost:3000';

module.exports = {

    resolve: {
        extensions: ['', '.js']
    },

    entry: ['webpack-hot-middleware/client','./src/client/js/Kindred'],

    devtool: 'cheap-module-source-map',

    module: {
        loaders:[
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'babel',
                query: {presets: ['es2015', 'react', 'react-hmre', 'stage-0']}
            },
            {test: /\.png$/, loader: "url-loader?limit=100000"},
            // Images
            {test: /\.jpg$/, loader: "file-loader"},
            {
                test: /\.(eot|svg|ttf|woff|woff2)$/,
                loader: 'file?name=./font/[name].[ext]'
            },
            // Stylesheets
            { test: /\.scss$/, loader: ExtractTextPlugin.extract('style', 
                [
                    'css?sourceMap&modules&importLoaders=1',
                    'sass?sourceMap&modules',
                ]
            ) },
            // Font Definitions
            { test: /\.svg$/, loader: 'url?limit=65000&mimetype=image/svg+xml&name=public/font/[name].[ext]' },
            { test: /\.woff$/, loader: 'url?limit=65000&mimetype=application/font-woff&name=public/font/[name].[ext]' },
            { test: /\.woff2$/, loader: 'url?limit=65000&mimetype=application/font-woff2&name=public/font/[name].[ext]' },
            { test: /\.[ot]tf$/, loader: 'url?limit=65000&mimetype=application/octet-stream&name=public/font/[name].[ext]' },
            { test: /\.eot$/, loader: 'url?limit=65000&mimetype=application/vnd.ms-fontobject&name=public/font/[name].[ext]' }
        ]
    },

    sassLoader: {
        includePaths: [ 'src/client/scss' ]
    },

    plugins: process.env.NODE_ENV === 'production' ? [
        new ExtractTextPlugin ('app.css', {allChunks: true}),
        new webpack.optimize.DedupePlugin (),
        new webpack.optimize.OccurrenceOrderPlugin (),
        new webpack.optimize.UglifyJsPlugin ()
    ] :  [
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NoErrorsPlugin(),
        new ExtractTextPlugin("style.css")
    ],

    devServer: {
        hot: true,
        contentBase: './public'
    },

    output: {
        path: path.join(__dirname),
        publicPath: '/',
        filename: 'bundle.js'
    }

};

节点cmd运行

webpack-dev-server --inline --history-api-fallback --port 3000

加载页面时

[HMR] Waiting for update signal from WDS...
home:1 GET http://localhost:3000/__webpack_hmr 
client:22 [WDS] Hot Module Replacement enabled.

它需要我运行，但不是：/

好的，人们很容易看到我为让它在这里工作所做的工作：

我认为完全删除 scss 并直接使用 css 模块对我来说更容易。这似乎有很大帮助。

我使用 git@github.com:christianalfoni/webpack-express-boilerplate.git 来帮助我指导自己。知道我有一个工作的东西实际上教给我的东西比我之前在 webpack 中学到的要多得多。你可以猜到这不是很多：D

此外，真正有帮助的一个主要变化是改变路径，这并不奇怪。但这些与output.path我之前读过的路径性有关，但认为这与wepack.config.js从那里开始的所有内容都算作文档根目录无关，即使对于 html 和 css 也是如此。

**关键部分 ：） **

我还必须更新我的快速设置，因为我没有给它一个express.static路径......哦，我的愚蠢，我怎么会错过这样一个基本的东西......所以：

表达

app.use(express.static(__dirname + '/public/')); //Don't forget me :(

最终的 CSS

/* Webfont: Lato-Black */@font-face {
    font-family: 'LatoBlack';
    src: url('/font/Lato-Black.eot'); /* IE9 Compat Modes */
    src: url('/font/Lato-Black.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
         url('/font/Lato-Black.woff2') format('woff2'), /* Modern Browsers */
         url('/font/Lato-Black.woff') format('woff'), /* Modern Browsers */
         url('/font/Lato-Black.ttf') format('truetype');
    font-style: normal;
    font-weight: normal;
    text-rendering: optimizeLegibility;
}

Wekpack.config

var path = require('path');
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');

    },
    postcss: function (webpack) {
        return [
            stripInlineComments
            , precss
            , autoprefixer
            , require('postcss-simple-vars')
            , require('postcss-nested'
            , autoprefixer({browsers: ['last 2 versions']}))
        ];
    }
};

我实际上已经两次发布了相同的答案。但它们都是相关的。可悲:(
