salut a tous,
je voudrais utiliser la librairie leaflet au sein de mon application reactjs. j'ai suivi toutes les étapes d’intégrations mentionnées ici : https://react-leaflet.js.org/docs/start-installation/.

aidez moi a comprendre et a résoudre l'erreur ci-dessous que je rencontre lorsque j’exécute mon application reactjs.

./node_modules/@react-leaflet/core/esm/path.js 10:41
Module parse failed: Unexpected token (10:41)
File was processed with these loaders:
* ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
| useEffect(function updatePathOptions() {
| if (props.pathOptions !== optionsRef.current) {
> const options = props.pathOptions ?? {};
| element.instance.setStyle(options);
| optionsRef.current = options;

Puis supprime le dossier node_modules/.cache et relance npm install puis npm start

Voici ce qui a marché pour moi.

Ouvre le package.json et remplace ce code

 "browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [ "last 1 chrome version", "last 1 firefox version", "last 1 safari version" ] },
