step2 修改webpack.base.conf.js文件配置的入口
// entry: {
// app: './src/main.js'
// },
entry: utils.entries(),
step3 修改webpack.dev.conf.js文件的打包方法 找到下面的代碼，將其注釋掉：
new HtmlWebpackPlugin({
 filename: 'index.html',
 template: 'index.html',
 inject: true
}),

// new HtmlWebpackPlugin({
 // filename: 'index.html',
 // template: 'index.html',
 // inject: true
 // }),
 new FriendlyErrorsPlugin()
 ].concat(utils.htmlPlugin())
step4 修改webpack.prod.conf.js 找到下面的代碼，注釋掉：
new HtmlWebpackPlugin({
filename: config.build.index,
template: 'index.html',
inject: true,
minify: {
 removeComments: true,
 collapseWhitespace: true,
 removeAttributeQuotes: true
 // more options:
 // https://github.com/kangax/html-minifier#options-quick-reference
},
// necessary to consistently work with multiple chunks via CommonsChunkPlugin
chunksSortMode: 'dependency'
}),

new CopyWebpackPlugin([{
  from: path.resolve(__dirname, '../static'),
  to: config.build.assetsSubDirectory,
  ignore: ['.*']
 }])
 ].concat(utils.htmlPlugin())
