Can't resolve all parameters for BsModalService

I'm adding a modal to my spfx angular 2 application. I was trying to follow

ngx-bootstrap-modal
through http://valor-software.com/ngx-bootstrap/#/modals. but I am getting this error:

Unhandled Promise rejection: Can't resolve all parameters for AppComponent: (?). ; Zone: <root> ; Task:


This is what my code looks like:

package.json

{
"name": "our-applications",
"version": "0.0.1",
"private": true,
"engines": {
"node": ">=0.10.0"

"gulp": "~3.9.1"
},
"scripts": {

}
}


my html that calls the function:

<button (click)="addApp();" class="ms-Button ms-Button--primary">
<span class="ms-Button-label">Add Application</span>
</button>


snippet of my app.component.js

import { Component, OnInit,ViewEncapsulation, ViewContainerRef } from '@angular/core';
import { AppSettings } from './shared/app.settings';
import { IApplicationEntity } from './shared/app.entities';
import { BsModalService } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/modal-options.class';

export class AppComponent implements OnInit {
bsModalRef: BsModalRef;

constructor(private modalService: BsModalService) {}

public addApp() {
console.log("open the modal");
let list = ['Open a modal with component', 'Pass your data', 'Do something else', '...'];
this.bsModalRef = this.modalService.show(ModalContentComponent);
this.bsModalRef.content.title = 'Modal with component';
this.bsModalRef.content.list = list;
}
}


and this is my app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ModalModule } from 'angular2-modal';
import { BootstrapModalModule } from 'angular2-modal/plugins/bootstrap';
import { AppComponent } from './app.component';
import { AppSettings } from './shared/app.settings';
import { AppLoadingComponent } from './shared/loading/app.loading';
import { AppNotifyComponent } from './shared/notify/app.notify';
import { BsModalService } from 'ngx-bootstrap/modal';


@NgModule({
imports: [BrowserModule
],
declarations: [
AppComponent,
AppLoadingComponent,
AppNotifyComponent],
bootstrap: [AppComponent],
})

export class AppModule {}

Answer Source

From your app.module.ts, you didn't add ModalModule to imports array, the solution should be import ModalModule from ngx-bootstrap and add it to your imports array.

import { ModalModule } from 'ngx-bootstrap';
// or
import { ModalModule } from 'ngx-bootstrap/modal';

imports: [BrowserModule, ModalModule.forRoot()],
