属性"管道"在类型"操作"上不存在<Action>

Question

我注意到问题 #990 但没有解决方案。

项目正在编译，但是当我尝试将 .pipe 与商店一起使用时，我收到一个 linting 错误，指出我的效果和组件中的"操作"类型上不存在属性"管道"。但是，当我在可观察对象上使用 .pipe 时，我在同一组件中没有遇到问题。

类型存储/操作上不存在 Linting 问题示例

this.item$ = this.store.pipe(select(item));
@Effect({ dispatch: false })
logout$ = this.actions$.pipe(
ofType<Logout>(AuthActionTypes.LogoutAction),
tap(() => {
localStorage.removeItem(USER);
this.router.navigate(['/']);
})
);

没有问题

this.item$.pipe(takeUntil(this.onDestroy$)).subscribe(status => {

Package.json 这是带有 rxjs 6 和 NgRx 库的 Angular 6

有同样的错误。就我而言，这是因为我从"@ngrx/store-devtools/src/reducer"而不是"@ngrx/效果"导入操作

import { Injectable } from '@angular/core';
import { createEffect } from '@ngrx/effects';
//import { Actions } from '@ngrx/store-devtools/src/reducer'; --> wrong
import { Actions, ofType } from '@ngrx/effects';
import { map, mergeMap } from 'rxjs/operators';
import { ProductService } from '../product.service';
import * as ProductActions from './product.actions';
@Injectable()
export class ProductEffects {
constructor(private actions$: Actions,
private productsService: ProductService) { }

loadProducts$ = createEffect(() => {
return this.actions$.pipe(
ofType(ProductActions.loadProducts),
mergeMap(() => this.productsService.getProducts().pipe(
map(products => ProductActions.loadProductsSuccess({ products }))
))
)
})

}
