Question

我正在使用ngrx，但出现以下错误[Angular 6]

ERROR in src/app/app.component.ts(3,10): error TS2305: Module '"C:/Angular Activity/NgRxExample/currency-conversion/src/app/actions/amount"'
has no exported member 'AmountChangeAction'.
src/app/app.module.ts(6,9): error TS2305: Module '"C:/Angular Activity/NgRxExample/currency-conversion/src/app/actions/amount"' has no exported member 'AmountChangeAction'.
src/app/reducers/amount.ts(4,58): error TS2694: Namespace '"C:/Angular Activity/NgRxExample/currency-conversion/src/app/actions/amount"' has
no exported member 'AmountChangeAction'.
src/app/reducers/amount.ts(7,21): error TS2339: Property 'AMOUNTCHANGE' does not exist on type 'typeof import("C:/Angular Activity/NgRxExample/currency-conversion/src/app/actions/amount")'

currency.ts

import {Currency} from './../models/currency';
import { Action } from '@ngrx/store';

export const  CURRENCIESUPDATE  = '[Currency] UpdateAll';
export const  CURRENCIESUPDATED = '[Currency] UpdatedAll';

export class CurrenciesUpdateAction implements Action {
    readonly type =  CURRENCIESUPDATE
}

export class CurrenciesUpdatedAction implements Action {
    readonly type =  CURRENCIESUPDATED
    constructor(public payload: Currency[]) {}
}

amount.ts：

import {Currency} from './../models/currency';
import { Action } from '@ngrx/store';

export const  CURRENCIESUPDATE  = '[Currency] UpdateAll';
export const  CURRENCIESUPDATED = '[Currency] UpdatedAll';

export class CurrenciesUpdateAction implements Action {
    readonly type =  CURRENCIESUPDATE
}

export class CurrenciesUpdatedAction implements Action {
    readonly type =  CURRENCIESUPDATED
    constructor(public payload: Currency[]) {}
}

请让我知道这有什么遗漏，我是第一次使用ngrx，所以如果它很傻，请原谅。

我正在使用角度6。

我的package.json：

    "@angular/animations": "~7.2.0",
    "@angular/common": "~7.2.0",
    "@angular/compiler": "~7.2.0",
    "@angular/core": "~7.2.0",

从共享的代码段来看，确实好像没有AmountChangeAction操作。

ngrx和导出成员错误[没有导出成员]
