当我尝试测试实现react-leaflet库的react组件时，遇到以下问题

({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){export { useMap, useMapEvent, useMapEvents } from './hooks.js';

SyntaxError: Unexpected token 'export'

  2 | import { makeStyles } from "@material-ui/core";
> 3 | import { MapContainer, TileLayer, Marker, Popup, useMap } from "react-leaflet";
    | ^

  5 | const Map = () => {
  6 |   const classes = useStyles();

  at Runtime.createScriptFromCode (node_modules/jest-runtime/build/index.js:1728:14)
  at Object.<anonymous> (src/components/accomodation/Map.js:3:1)

我在互联网上搜索问题，发现的建议对我不起作用。

当我尝试渲染与该库有关系的任何组件（例如 App.test.js）时，会发生此错误

import { render, screen, prettyDOM } from '@testing-library/react';
import '@testing-library/jest-dom/extend-expect'
