我尝试连接到firebase中的数据库 . 这是app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { StatusBar } from '@ionic-native/status-bar';

import { AngularFireDatabase, AngularFireDatabaseModule } from 'angularfire2/database';

import { AngularFireModule } from 'angularfire2';
import { environment } from '../environments/environment';

import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';

@NgModule({
  declarations: [
    MyApp,
    HomePage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
    AngularFireModule.initializeApp(environment.firebase),
    AngularFireDatabaseModule
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage
  ],
  providers: [
    AngularFireDatabase,
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

错误就在这一行

import { AngularFireDatabase, AngularFireDatabaseModule } from 'angularfire2/database';

我试过这个也从'angularfire2 / database-deprecated '导入{AngularFireDatabase，AngularFireDatabaseModule};

但错误只是改变了 .

运行时错误无法找到模块“angularfire2 / database”堆栈错误：无法在webpack_require（http：// localhost：8100 / build / main.js：78：7）的Object.217（http：// localhost：8100 / build / main.js：78：7）中找到模块“angularfire2 / database” //localhost:8100/build/vendor.js:55:30）at object.194（http：// localhost：8100 / build / main.js:60:70）at webpack_require（http：// localhost：8100 / build / vendor.js：55：30）在webpackJsonpCallback（http：// localhost：8100 / build / vendor.js：26：23）的http：// localhost：8100 / build / main.js：1：1

    刚看完这个documentation

    在终端： npm install firebase --save

    在你的app.module.ts中创建firebase配置对象：

    // Set the configuration for your app
// TODO: Replace with your project's config object
var config = {
  apiKey: "apiKey",
  authDomain: "projectId.firebaseapp.com",
  databaseURL: "https://databaseName.firebaseio.com",
  storageBucket: "bucket.appspot.com"
};
firebase.initializeApp(config);

// Get a reference to the database service
var database = firebase.database();

    After the call on Page .ts:

    import * as firebase from 'firebase';
    回复于
