How to import openlayers module in Angular using curly braces

Question

I have an angular 7 Project that includes openlayers.

npm install ol

So I am using openayers components like this:

import { Component, OnInit } from '@angular/core';
import Map from 'ol/Map';
import View from 'ol/View';

And I am creting a Map object: var map = new Map(opitons);

But I want to use curly braces for import modules like this:

import {  Map, View } from 'openlayers';

But this throws an exception like this:

Module not found: Error: Can't resolve 'openlayers'
