Question

Я занимаюсь угловым проектом.И теперь я имею в виду учебник по созданию file upload детали с firebase.Я уже установил этот пакет "@angular/fire": "^5.1.2", для проекта.но учебник объясняет, как установить npm i firebase angularfire2 для проекта.Я попытался сделать это и получил такую ​​ошибку.

PS C:\Users\ruwan\Documents\projects\new project\Hair-4-U-hospital\Admin\Hair-4-U-Manufacture>

Однако я хочу сделать такой компонент в соответствии с руководством.

import { Component } from '@angular/core';
import { AngularFireStorage } from 'angularfire2/storage';

@Component({
selector: 'app-root',
template: `
<label for="file">File:</label>
<input type="file" (change)="upload($event)" accept=".png,.jpg" />
`
})
export class AppComponent {
    constructor(private afStorage: AngularFireStorage) { }
    upload(event) {
        this.afStorage.upload('/upload/to/this-path', event.target.files[0]);  
    }
}

Я не могу получить AngularFireStorage откуда в настоящее время существуют пакеты внутри "@angular/fire": "^5.1.2"
