I installed ngx echarts in an Angular 14 project but I get this error Generic type 'ɵɵDirectiveDeclaration' requires between 6 and 8 type arguments - echarts

After doing the install using
npm install echarts -S
npm install ngx-echarts -S

As soon as I import the native plugin and update the application it stops working.

Steps to reproduce:
Create a test project. ionic start TestProject blank
Add a test provider. ionic generate provider TestProvider. The provider is added to the provider list in the app.module.
Inject the provider into the home page component, by importing TestProvider and injecting into the constructor.
Sometimes the error occurs; sometimes it doesn't. If it doesn't, create another provider and repeat the process until the error occurs.
At one point, I created three separate test providers with identical, copy/pasted code; one of them worked consistently, but the other two produced the StaticInjectorError.

I'm running on Windows 10, with Node.js version 8.9.4 and npm version 5.6.0.
Any help would be greatly appreciated.

ionic: module has no exported member

I am a newbie of ionic framework, just started now. I am working on windows. I created my app with this command:
ionic start ionic-welcome tabs
ionic serve
I create a new page with below command
ionic g page welcome
I get this response in my console:
[OK] Generated a page named welcome!
updated app.module.ts for welcome page:
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 { Welcome } from '../pages/welcome/welcome';
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';
#NgModule({
declarations: [
MyApp,
Welcome,
AboutPage,
ContactPage,
HomePage,
TabsPage
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
Welcome,
AboutPage,
ContactPage,
HomePage,
TabsPage
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
But when i browse to localhost:8100 i am getting this error for "welcome page".
Module
'"C:/xampp/htdocs/ionic/ionic-welcome/src/pages/welcome/welcome"' has

Some says to remove '^' character from package.json but don't have one. I am out of options don't know what to do next, please help.
if you check Welcome.ts you probably find something like this
export class WelcomePage {
constructor(public navCtrl: NavController, public navParams: NavParams)
{
}
ionViewDidLoad() {
console.log('ionViewDidLoad WelcomePage');
}
in your app.modules.ts do the following
import { WelcomePage } from '../pages/welcome/welcome'
then add WelcomePage to declarations and entryComponents.
i just faced this problem and managed to solve it this way.
Good luck

get router's IP Address in ionic2 - Non Native Plugin

Plugin:
cordova plugin add cordova-plugin-networkinterface
Code:
networkinterface.getIpAddress((ip) => {
console.log(ip);
});
Error:
TypeError: Cannot read property 'getIPAddress' of undefined
Now here neither I have provide any provider nor any import, so how does it work in ionic 2 ?
It's not A native plugin. But this plugin is working in ionic 2 also according to this link

Latest Code File :
declare var networkinterface: any;
#Component({
templateUrl: 'app.html'
})
export class MyApp {
public rootPage:any = HomePage;
constructor(private platform: Platform,private statusBar: StatusBar,private splashScreen: SplashScreen, private network: Network, private iab: InAppBrowser, private http: Http, private toast: Toast) {
platform.ready().then(() => {
networkinterface.getWiFiIPAddress((ip) => {
console.log(ip);
});
}
You have to use it like below after installing the non-native plugin.
This method (getIpAddress()) is deprecated and uses the
getWiFiIPAddress() method.
declare let networkinterface: any;
#Component({
...
})
export class TestPage {
...
getIpAddress() {
networkinterface.getWiFiIPAddress((ip) => {
console.log(ip);
});
}
}
You can try using external url:
async function getIP(){
const repsIP = await fetch('https://api.ipify.org/?format=json');
const data = await repsIP.json();
return data;
}
Wherever you want, call this function:
this.getIP().then(data => this.ipAddress = data.ip);
