next build할 때 웹팩 에러가 발생합니다.

root@ip-172-31-39-250:/home/ubuntu/Nodebird/front# npm run build

> react-nodebird-front@1.0.0 build /home/ubuntu/Nodebird/front

> cross-env ANALYZE=true next build

Creating an optimized production build ...

Webpack Bundle Analyzer saved report to /home/ubuntu/Nodebird/front/.next/analyze/server.html

Failed to compile.

./node_modules/@ant-design/icons/lib/dist.js 5:6

Module parse failed: 'import' and 'export' may only appear at the top level (5:6)

You may need an appropriate loader to handle this file type.

|     // 加载script标签会阻塞js执行，antd部分组件（如表格）无法在一轮循环内完成完整的渲染，故延时

|     setTimeout(function(){

아래 질문이랑 참고해서 웹팩버전을 바꿨는데.. 그래도 같은 오류가 발생합니다.
