How to compile static index.html page with vuejs and webpack?

Question

webpack

Hello!
I need to compile a static page for the index.html project. I use vuejs and webpack.
I'm using the html-webpack-plugin plugin.
But when npm run build gives an error:

ERROR in build.js from UglifyJs
Unexpected token: punc (() [src/app.vue:14,0][build.js:13657,6]
Child html-webpack-plugin for "index.html":

webpack.config.js:

var path = require('path')
var webpack = require('webpack')
const 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$/,
        use: [
          'vue-style-loader',
          'css-loader'
        ],
      },
      {
        test: /\.scss$/,
        use: [
          'vue-style-loader',
          'css-loader',
          'sass-loader'
        ],
      },
      {
        test: /\.sass$/,
        use: [
          'vue-style-loader',
          'css-loader',
          'sass-loader?indentedSyntax'
        ],
      },
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
            // Since sass-loader (weirdly) has SCSS as its default parse mode, we map
            // the "scss" and "sass" values for the lang attribute to the right configs here.
            // other preprocessors should work out of the box, no loader config like this necessary.
            'scss': [
              'vue-style-loader',
              'css-loader',
              'sass-loader'
            ],
            'sass': [
              'vue-style-loader',
              'css-loader',
              'sass-loader?indentedSyntax'
            ]
          }
          // other vue-loader options go here
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'file-loader',
        options: {
          name: './img/[name].[ext]?[hash]'
        }
      },
      {
        test: /\.(ttf|otf|eot|woff|woff2)$/,
        use: {
          loader: "file-loader",
          options: {
            name: "./fonts/fonts/[name].[ext]",
          },
        },
      }
    ]
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: __dirname + "/index.html",
      inject: 'body'
  })
   ],
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    },
    extensions: ['*', '.js', '.vue', '.json']
  },
  devServer: {
    noInfo: true,
    historyApiFallback: true,
  },
  performance: {
    hints: false
  },
  devtool: '#eval-source-map'
}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  module.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
    })
  ])
}

What am I doing wrong?
