facebook - ionic3 cordova-plugin-facebook4 facebook 安装问题错误

Question

我似乎遇到了原生插件的问题。

日志路径:/Users/philipwilson/workspace/ionic/test2/platforms/ios/cordova/console.log

        [21:12:05]  console.log: Angular is running in the development mode. Call enableProdMode() to enable the production 
                    mode. 
        [21:12:05]  console.log: Ionic Native: deviceready event fired after 542 ms 
        [21:12:05]  console.warn: Native: tried calling Facebook.browserInit, but the Facebook plugin is not installed. 
        [21:12:05]  console.warn: Install the Facebook plugin: 'ionic plugin add cordova-plugin-facebook4' 

我已经尝试了很多东西。

 518  ionic cordova plugin add cordova-plugin-facebook4 --variable APP_ID="99999999999" --variable APP_NAME="test2.com"
 565  ionic cordova build ios
 578  npm install --save @ionic-native/facebook
 593  ionic plugin add cordova-plugin-facebook4
 594  ionic cordova emulate ios -lc

我遵循了几个例子，但仍然看到 ionic 3 和 angular4 的问题

这是我的信息:~/workspace/ionic/test2$ ionic 信息

全局包:

@ionic/cli-utils : 1.5.0
Cordova CLI      : 7.0.1 
Ionic CLI        : 3.5.0

本地包:

@ionic/cli-plugin-ionic-angular : 1.3.2
Cordova Platforms               : ios 4.4.0
Ionic Framework                 : ionic-angular 3.4.2

系统:

OS         : OS X El Capitan
Xcode      : Xcode 8.2.1 Build version 8C1002 
ios-deploy : 1.8.3 
ios-sim    : 3.1.1 
npm        : 5.0.0 

我也看过这些例子: https://ionicframework.com/docs/native/facebook/ https://ionicthemes.com/tutorials/about/ionic2-facebook-login

有人帮忙吗？

这就是我所做的，确保在 app.module.ts 文件中公开 Facebook 模块。

app.module.ts

import { NgModule, ErrorHandler } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { MyApp } from './app.component';

import { AboutPage } from '../pages/about/about';
import { ContactPage } from '../pages/contact/contact';
import { HomePage } from '../pages/home/home';
import { TabsPage } from '../pages/tabs/tabs';

import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

import { Facebook, FacebookLoginResponse } from '@ionic-native/facebook';

@NgModule({
  declarations: [
    MyApp,
    AboutPage,
    ContactPage,
    HomePage,
    TabsPage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp)
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    AboutPage,
    ContactPage,
    HomePage,
    TabsPage
  ],
  providers: [
    StatusBar,
    SplashScreen,
    Facebook,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

在你的 home.ts 中:

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Facebook, FacebookLoginResponse } from '@ionic-native/facebook';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  constructor(public navCtrl: NavController, private fb: Facebook) {
    this.fb = fb

    console.log(fb)

    this.fb.login(['public_profile', 'user_friends', 'email'])
      .then((res: FacebookLoginResponse) => 
        console.log('Logged into Facebook!', res)
      )
      .catch(e => console.log('Error logging into Facebook', e));


    this.fb.logEvent(this.fb.EVENTS.EVENT_NAME_ADDED_TO_CART);
  }

}

如果您忘记在 app.module.ts 文件中包含 Facebook 提供程序，您将收到错误消息:“No provider for Facebook!”

作为旁注，请确保您使用模拟器或设备来测试登录操作，否则它将无法工作。
