I have nextjs app + typescript + react-leaflet

when I start my development server npm run dev it's fine there is no error, but when I start build with npm run build I have an error, it says.

Type error: Module '"react-leaflet"' has no exported member 'useEventHandlers'.

Here's my package.json file.

  "version": "0.1.0",
  "private": true,

    "build": "next build",
    "start": "next start"
  },

  },
  "devDependencies": {
    "@types/react": "17.0.8",
    "typescript": "4.3.2"
  }
}

I already install @types/react-leaflet, but why did this happened?

react-leaflet in fact does not export useEventHandlers method. It's a method from @react-leaflet/core package. It's a dependency of react-leaflet package and must be installed along with it. And should be imported from there:

import { useMap, useMapEvent, MapContainer } from 'react-leaflet'
import { useEventHandlers } from '@react-leaflet/core'
