Map component: Cannot read property 'initialize' of undefined












1
















I'm trying to get a basic map working using react-leaflet.js. Here's my code:



import React from 'react';

import { Map } from 'leaflet';



const mapStyle = {

  height: '400px'

};



const mapCenter = [0, -0];

const zoomLevel = 3;



export default class MapT extends React.PureComponent {

  render() {

    return (

      <div>

        <Map

          style={mapStyle}

          center={mapCenter}

          zoom={zoomLevel}

        >

        </Map>

      </div>

    );

  }

}


But I'm getting an error:



Uncaught TypeError: Cannot read property 'initialize' of undefined

What am I doing wrong?

    Have you tried importing from react-leaflet instead of leaflet?

            0 $begingroup$ I'm fairly new to coding and I wrote this script in Python for a house with a roof in Minecraft Pi. I've found different ways to write the coordinates to make the code base shorter, but I'm wondering if it is possible for me to refactor it any further so I don't have to list each coordinate line by line. import mcpi.minecraft as minecraft import mcpi.block as block mc = minecraft.Minecraft.create() p = mc.player.getTilePos() mc.setBlocks(p.x+1, p.y, p.z+1, #Main structure starting coordinates (DO NOT ALTER) p.x+19, p.y+4, p.z+6, #Structure size/coordinates (Alters cube size) block.STONE_BRICK) mc.setBlocks(p.x+2, p.y+1, p.z+2, #Hollowing out main structure interior p.x+18, p.y+3, p.z+5, block.AIR) mc.setBlocks(p.x, p.y...
