开发笔记:Firebase导入未在构造函数离子原生中初始化

我正在研究离子fcm推送通知。我已经进口了

import { Firebase } from '@ionic-native/firebase';但我无法在构造函数中初始化Firebase。这是我的代码

import { Injectable } from '@angular/core';
import { Firebase } from '@ionic-native/firebase';
import { Platform } from 'ionic-angular';
import {HttpClient, HttpHeaders} from '@angular/common/http';
@Injectable()
export class FcmProvider {
constructor(private platform: Platform,
public firebaseNative:Firebase,
public http: HttpClient) {
console.log('Hello FcmProvider Provider');
}
// Get permission from the user
async getToken() {
let token;
if (this.platform.is('android')) {
token = await this.firebaseNative.getToken()
}
}
}
}


我收到错误

constructor(private platform: Platform,
public firebaseNative:Firebase,


这是说

找不到名字Firebase

我关注this article。

我安装了npm i @ ionic-native / firebase和npm i @ ionic-native / fcm包仍然没有得到它。有关更多信息，请参见截图

更新：请Package.Json
