ngrx/effects 5.2.0 报告 ts2684

Question

为什么一直报ts2684:the'this'context of type'void' is not assignable to method'this'？

 @Effect()
  loadList$: Observable<Action> = this.action$.ofType('LOAD').pipe(
    map(()=>{
      console.log(1);
      return new LoadSuccess();
    })
 ); 

Answer 1

我知道原因:) map 应该从 'rxjs/operators' 而不是 'rxjs/operators/map' 导入
