Answer 1

您需要添加Facebook在你的AppModule(app.module.ts文件):

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


@NgModule({
    declarations: [...],
    imports: [...],
    bootstrap: [IonicApp],
    entryComponents: [...],
    providers: [
        // ...
        Facebook // <--- Here!
        // ...
        { provide: ErrorHandler, useClass: IonicErrorHandler }
    ]
})
export class AppModule { }

Answer 2

所选答案适用于 Ionic3。对于Ionic 4 +：在任何具有使用 FB 登录的组件 的模块中，添加：

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

[注意/ngx]

并添加该 @NgModule 的提供者

providers: [ Facebook, .... ]
