Can't run Vuetify + Leaflet >> Webpack error

Question

I followed the instructions from https://www.npmjs.com/package/vue2-leaflet https://vue2-leaflet.netlify.app/quickstart/#installation

main.js import 'leaflet/dist/leaflet.css';

MyComponent.vue

<template>

import latLng from 'leaflet'; // https://vue2-leaflet.netlify.app/quickstart/#installation
import { LMap, LTileLayer, LMarker, LPopup, LTooltip } from 'vue2-leaflet';

components: {
      LMap,
      LTileLayer,
      LMarker,
      LPopup,
      LTooltip
}

data: () => ({
      zoom: 13,
      center: latLng(47.41322, -1.219482),
      url: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',

      showParagraph: false,
      mapOptions: {
        zoomSnap: 0.5

      showMap: false
}

Actual Results

vue.runtime.esm.js?2b0e:619 [Vue warn]: Error in data(): "TypeError: leaflet__WEBPACK_IMPORTED_MODULE_32___default(...) is not a function"

found in

<MyComponent> at src/views/apps/deal/MyComponent.vue <VMain> <VApp> <Layout> at src/layouts/full-layout/Layout.vue <VApp> <App> at src/App.vue <Root>

→ seems latLng function is unknown

Versions

• Leaflet: v1.7.1
• Vue: v2.6.12
• Vuetify: v2.4.0
• Vue2Leaflet: v2.7.0

Answer 1

The import line:

import latLng from 'leaflet';

Should have been a named import instead:

import { latLng } from 'leaflet';

(Note the curly braces)
