      favicon:'src/assets/images/favicon.ico',
      inject: true
    }),

然后找到webpack.prod.conf.js，再找到HtmlWebpackPlugin，添加favicon:‘favicon.ico路径’,

new HtmlWebpackPlugin({
      filename: process.env.NODE_ENV === 'testing'
        ? 'index.html'
        : config.build.index,
      template: 'index.html',
      favicon:'src/assets/images/favicon.ico',
      inject: true,
      minify: {
        removeComments: true,
        collapseWhitespace: true,
