集成Ionic2 Auth服务时出错

Question

我试图将facebook登录集成到我的离子2应用程序中。我正在关注指南here，一切都很好，直到我盯着在构造函数中使用Auth和User。

问题是，目前当我在构造函数中使用public auth: Auth, public user: User时，它会给出问题

  

未捕获错误：无法找到模块＆＃34; ionic-native＆＃34;

以下是我的完整代码

import { Component } from '@angular/core';
import { Auth, User } from '@ionic/cloud-angular';
@Component({
  selector: 'social-auth',
  templateUrl: 'social.html',
})
export class SocialAuth {
  constructor(public auth: Auth, public user: User) {
  }
  openTwitter(){
    this.auth.login('twitter').then((data) => {
     console.log(data);
    });
  }
}

您的 package.json 中包含无效的包。

"ionic-native": "^3.5.0",

从版本3.x开始， ionic-native分为@ionic-native/core和@ionic-native/package_name。因此ionic-native 3.x不存在。

从package.json中删除"ionic-native": "^3.5.0",条目。

清除node_modules文件夹并运行npm install

同样在我的评论中提到： 你 dont 需要再次将Auth设置为提供商..它将由云模块负责
