As we're going to use a modal, We've to update app.module.ts used in ngx-bootstrap Dropdowns chapter to use ModalModule and BsModalService.
Update app.module.ts to use the ModalModule and BsModalService.
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { TestComponent } from './test/test.component';
import { AccordionModule } from 'ngx-bootstrap/accordion';
import { AlertModule,AlertConfig } from 'ngx-bootstrap/alert';
import { ButtonsModule } from 'ngx-bootstrap/buttons';
import { FormsModule } from '@angular/forms';
import { CarouselModule } from 'ngx-bootstrap/carousel';
import { CollapseModule } from 'ngx-bootstrap/collapse';
import { BsDatepickerModule, BsDatepickerConfig } from 'ngx-bootstrap/datepicker';
import { BsDropdownModule,BsDropdownConfig } from 'ngx-bootstrap/dropdown';
import { ModalModule, BsModalService } from 'ngx-bootstrap/modal';

@NgModule({
   declarations: [
      AppComponent,
      TestComponent
   ],
   imports: [
      BrowserAnimationsModule,
      BrowserModule,
      AccordionModule,
      AlertModule,
      ButtonsModule,
      FormsModule,
      CarouselModule,
      CollapseModule,
      BsDatepickerModule.forRoot(),

      ModalModule
   ],
   providers: [AlertConfig, BsDatepickerConfig, BsDropdownConfig,BsModalService],
   bootstrap: [AppComponent]
})
export class AppModule { }
Update test.component.html to use the modal.
test.component.html
<button type="button" class="btn btn-primary" (click)="openModal(template)">Open modal</button>

<ng-template #template>
   <div class="modal-header">
      <h4 class="modal-title pull-left">Modal</h4>
      <button type="button" class="close pull-right" aria-label="Close" (click)="modalRef.hide()">

   <div class="modal-footer">
      <button type="button" class="btn btn-default" (click)="modalRef.hide()">Close</button>

import { Component, OnInit, TemplateRef } from '@angular/core';
import { BsModalRef, BsModalService } from 'ngx-bootstrap/modal';

@Component({
   selector: 'app-test',
   templateUrl: './test.component.html',
   styleUrls: ['./test.component.css']
})
export class TestComponent implements OnInit {

   modalRef: BsModalRef;
   constructor(private modalService: BsModalService) {}

   openModal(template: TemplateRef<any>) {
      this.modalRef = this.modalService.show(template);
   }
