问题
I am trying ti use dragula in my angular2 app. Here is the app.module in my code:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { DragulaService, DragulaModule } from 'ng2-dragula/ng2-dragula';
import { AppComponent } from './app.component';
import { PlayComponent } from './play/play.component';
import {SelectedInstrumentsService} from './selected-instruments.service';
import {SizeService} from './size.service';
import {AudioFinderService} from './audio-finder.service';
@NgModule({
declarations: [
AppComponent,
PlayComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule,DragulaModule
],
providers: [DragulaService,SelectedInstrumentsService,SizeService,AudioFinderService],
bootstrap: [AppComponent]
})
export class AppModule { }
unfortunatly, when i add the DragulaService
to the providers
, or DragulaModule
to the imports
i face with the following errors:
Uncaught TypeError: ctorParameters.map is not a function

I am sure, i have installed the dragula
correctly.

There is an opend issue : https://github.com/valor-software/ng2-dragula/issues/496
You may use Angular 2.1.1 and Dragula 1.2.0 with something like the following in your package.json :
"dependencies": {
"@angular/common": "2.2.1",
"@angular/compiler": "2.2.1",
"@angular/core": "2.2.1",
"@angular/forms": "2.2.1",
"@angular/http": "2.2.1",
"@angular/platform-browser": "2.2.1",
"@angular/platform-browser-dynamic": "2.2.1",
"ng2-dragula": "1.2.0",
...
