Javascript Can'；t解析Angular 2中地图页的所有参数：（？，导航控制器，启动导航器…）

因此，我将Angular2与Ionic2一起用于我的移动应用程序。我的应用程序一直在编译和运行，直到我在应用程序中添加了一个新模块，以便在谷歌地图中导航。我正在使用phonegap launch navigator来实现这一点。我导入模块的类是我的Maps类，该类的结构如下所示

import { LaunchNavigator, LaunchNavigatorOptions} from 'ionic-native';
import { Component, NgZone } from "@angular/core";
import { NavController, Platform, NavParams } from 'ionic-angular';
import {GoogleMap, GoogleMapsEvent, GoogleMapsLatLng, GoogleMapsMarkerOptions, CameraPosition } from 'ionic-native';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import { Geolocation } from 'ionic-native';
import { Injectable,forwardRef,Inject } from "@angular/core";


@Component({
  selector: 'maps-page',
  templateUrl: 'maps.html',
})

export class MapsPage {

  private map: GoogleMap;
  destination:string;
  start:string;

  constructor(public LaunchNavigatorOptions: LaunchNavigatorOptions,
    private _navController: NavController,
    private LaunchNavigator:LaunchNavigator,
    private platform: Platform,
    public navCtrl: NavController,
    public navParams: NavParams,
    private _zone: NgZone) {
    this.start = "";
    this.destination = "Westminster, London, UK";
    this.platform.ready().then(() => this.onPlatformReady());
  }

我的package.json如下所示

导入这两个模块并将其放入构造函数后，我甚至无法启动我的应用程序，它会出现一个运行时错误，显示“无法解析MapsPage的所有参数（？，NavController，LaunchNavigator，Platform，NavController，NavParams，NgZone）。我认为问题出在LaunchNavigatorOptions上，因为当我特别指出该选项时，应用程序可以毫无问题地再次运行。我能做些什么来让它工作吗？非常感谢任何帮助。谢谢！

看起来您使用的是ionic native v2.2.11

在这个版本中，插件是全局的和静态的，不应该被注入构造函数中。 移除

public LaunchNavigatorOptions: LaunchNavigatorOptions

及

从你的构造器

检查是否升级到ionic native 3.x
