+In the output directory, you will see `stats.json` and `report-web.html` files.

+If you don't need the `report-web.html`, you can set `analyzerMode` to `disabled`.

+```js
+export default {

+      generateStatsFile: true,

 ## Notes
 
 1. Enabling the server mode will cause the `build` process to not exit normally.

 ## 注意事项
 
 1. 开启 Server 模式会导致 `build` 进程不能正常退出。
