Cannot read property 'prototype' of undefined

FallenRiteMonk commented 7 years ago

Importing the Module leads the following error:

EXCEPTION: Uncaught (in promise): TypeError: Cannot read property 'prototype' of undefined

The error seems to be thrown on the following line of the feature component:

d.prototype = b === null ? Object.create(b) : (__.prototype = b.prototype, new __());

to be preciser it's line 5 possition 69

Thank you

I can't reproduce your error. Could you provide a minimal example that reproduces the error ?

Here is an example that works for me: in app.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AngularOpenlayersModule } from 'angular2-openlayers';
import { AppComponent } from './app.component';

@NgModule({
  declarations:  [ AppComponent ],
  imports: [ BrowserModule, AngularOpenlayersModule ],
  bootstrap: [ AppComponent ]
})
export class AppModule { }

in app.component.ts:

import { Component } from '@angular/core';
import { MapComponent, ViewComponent, LayerTileComponent, LayerVectorComponent, 
          SourceOsmComponent, SourceVectorComponent, FeatureComponent,
          GeometryPointComponent, GeometryLinestringComponent, 
          CoordinateComponent, CollectionCoordinatesComponent } from 'angular2-openlayers';

@Component({
  selector: 'app-root',
  template: `
  <h1>Angular2-openlayers example</h1>
  <div style='height:300px'>
      <aol-map>
        <aol-view zoom="13">
          <aol-coordinate [x]="5" [y]="45" [srid]="'EPSG:4326'"></aol-coordinate>
        </aol-view>
         <aol-layer-tile>
            <aol-source-osm></aol-source-osm>
        </aol-layer-tile>
          <aol-layer-vector>
            <aol-source-vector>
                <aol-feature>
                    <aol-geometry-point>
                        <aol-coordinate [x]="5" [y]="45" [srid]="'EPSG:4326'"></aol-coordinate>
                    </aol-geometry-point>
                </aol-feature>
            </aol-source-vector>
          </aol-layer-vector>
      </aol-map>
   </div>`
})
export class AppComponent {}

in index.html:

<body>
  <app-root>Loading...</app-root>
</body>

I figured out what was the problem, it was due to a second import of openlayers that I already had, so removing that fixed the problem.

But would you please be so kind and putt the example in your readme file, that would already help.

Thanks

And your imports in the app component are not needed! You can remove them and your example still works!

@FallenRiteMonk Thanks for the feedback, I will add this short example to the readme. Can I close this issue ?
