Почему не видит функцию getJSON?

VSCode + TS + JQuery

jquery установил через npm

Получаю ошибку при компиляции $.getJSON is not a function

import * as $ from 'jquery';
class Test {
    name: string;
    public static get(): void {
        $.getJSON('countries.json', function(data) {                
            console.log('test');
        });
    } 
}

tsconfig

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "sourceMap": true,
        "allowSyntheticDefaultImports": true
    }
}   

package.json

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
