Call to createContext in react-leaflet/es/context.js fails

Question

TypeError: Object(...) is not a function

./node_modules/react-leaflet/es/context.js node_modules/react-leaflet/es/context.js:8

// $FlowFixMe: import
forwardRef } from 'react';

var _createContext = createContext({}), // This line fails
    Consumer = _createContext.Consumer,
    Provider = _createContext.Provider;

Answer 1

Just ran into this, you need to upgrade to React 16.3 or above as react-leaflet is using the context API.

npm i -S react react-dom

That should do it.
