Question

zone.js@0.6.25?main=browser:355 Unhandled Promise rejection: Template parse errors: 'ng-template' is not a known element: 1.

("[ERROR ->] ; Task: Promise.then ; Value: Error: Template parse errors: 'ng-template' is not a known element:

我已经在我的 App.module.ts 中应用了这个 FIX:

import { NgModule, CUSTOM_ELEMENTS_SCHEMA ,NO_ERRORS_SCHEMA}  from '@angular/core';


@NgModule({
    imports: [
        BrowserModule,
        FormsModule,
        ReactiveFormsModule,
        HttpModule,
        JsonpModule,
        CKEditorModule,
        Ng2DatetimePickerModule,
        Ng2DragDropModule,
        DragulaModule,
        ModalModule.forRoot(),
        MaterialModule.forRoot(),
        BootstrapModalModule,
        RouterModule.forRoot(appRoutes, {useHash: true})
    ],
    declarations: [something
    ],
    providers: [],
    bootstrap: [AppComponent],
    schemas: [ CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA ]
})
