问题描述
我尝试使用Ionics本机插件网络,但是由于据说缺少提供程序而失败。为了避免发生任何错误,我已经安装了Ionic的全新安装以及所需的依赖项:
I've tried using Ionics native plugin "Network" but it fails because of a supposedly missing provider. In order to avoid any mistakes I've installed a fresh installation of Ionic and the required dependencies:
ionic cordova plugin add cordova-plugin-network-information
npm install @ionic-native/network
然后我已经
import { Component } from '@angular/core';
import { Network } from '@ionic-native/network/ngx';
@Component({
selector: 'app-home',
templateUrl: 'home.page.html',
styleUrls: ['home.page.scss'],
})
export class HomePage {
constructor(private network: Network) {
// to nothing ...
}
}
...,并且在执行 ionic serve后将得到以下错误消息
:
... and will get the following error message after executing ionic serve
:
ERROR Error: Uncaught (in promise):
Error: StaticInjectorError(AppModule)[HomePage -> Network]:
StaticInjectorError(Platform: core)[HomePage -> Network]:
NullInjectorError: No provider for Network!
Error: StaticInjectorError(AppModule)[HomePage -> Network]:
StaticInjectorError(Platform: core)[HomePage -> Network]:
NullInjectorError: No provider for Network!
