• 升级UglifyJs版本，修改package.json

• 修改webpack.prod.conf.js

var UglifyJSPlugin = require('uglifyjs-webpack-plugin')
# plugins中修改插件
        new UglifyJSPlugin({
          uglifyOptions: {
            compress: {
              drop_debugger: true, // 注释debugger
              drop_console: true, // 注释console
              pure_funcs:['console.log'] // 移除console
            },
          },
          sourceMap: false,   // 去除打包后生成的.map文件
          parallel: true,
        }),

• 运行npm run build，完成！
