没有导出你的最后2个插件，并且没有指定html文件名dist，因为HtmlWebpackPlugin应该生成相对于path，下面是固定配置：

 var path = require('path')var webpack = require('webpack')var HtmlWebpackPlugin = require('html-webpack-plugin');module.exports = {entry: './src/main.js',output: {path: path.resolve(__dirname, './dist'),publicPath: '/dist/',filename: 'build.js'},module: {rules: [{test: /\.css$/,use: ['vue-style-loader','css-loader'],}, {test: /\.vue$/,loader: 'vue-loader',options: {loaders: {}// other vue-loader options go here}},{test: /\.js$/,loader: 'babel-loader',exclude: /node_modules/},{test: /\.(png|jpg|gif|svg)$/,loader: 'file-loader',options: {name: '[name].[ext]?[hash]'}}]},resolve: {alias: {'vue$': 'vue/dist/vue.esm.js'},extensions: ['*', '.js', '.vue', '.json']},devServer: {historyApiFallback: true,noInfo: true,overlay: true},performance: {hints: false},devtool: '#eval-source-map',plugins: [new webpack.ProvidePlugin({Vue: ['vue/dist/vue.esm.js', 'default'],jQuery: 'jquery','window.jQuery': 'jquery',$: 'jquery',moment: 'moment',}),new HtmlWebpackPlugin({hash: true,filename: 'index.html'})]}if (process.env.NODE_ENV === 'production') {module.exports.devtool = '#source-map'// http://vue-loader.vuejs.org/en/workflow/production.htmlmodule.exports.plugins = (module.exports.plugins || []).concat([new webpack.DefinePlugin({'process.env': {NODE_ENV: '"production"'}}),new webpack.optimize.UglifyJsPlugin({sourceMap: true,compress: {warnings: false}}),new webpack.LoaderOptionsPlugin({minimize: true})])}
