angular - typeof app.module 类型不存在属性

Question

import { StoreModule } from "@ngrx/store";
import { currentPurchase } from "../shared/index";

@NgModule({
 imports: [
        IonicModule.forRoot(MyApp, {}),
        HttpModule,
        StoreModule.provideStore({currentPurchase})
    ]
..

我得到Property currentPurchase' does not exist on type typeof app.module.进口的减速器看起来像这样：

import { ActionReducer, Action } from "@ngrx/store";
import { ActionType } from "./action-type";
import { PurchaseModel } from "../purchase/purchase.model";

export const currentPurchase: ActionReducer<PurchaseModel> = (state:PurchaseModel = new PurchaseModel(), action:Action) => {

    switch (action.type) {

        case ActionType.SET_PURCHASE:
            return (action.payload !== null) ? action.payload : new PurchaseModel();
        case ActionType.UPDATE_PURCHASE:
            return Object.assign({}, state, action.payload);
        default:
            return state;
    }
};

在减速器中使用无类型function而不是类型const，例如：

ng2-final AoT 失败：

export const settings: ActionReducer<SettingsModel> = (state:SettingsModel = new SettingsModel(), action:Action) => {

    switch (action.type) {
        case ActionType.SET_SETTINGS:
            return (action.payload !== null) ? action.payload : new SettingsModel();
        case ActionType.UPDATE_SETTINGS:
            console.log(Object.assign(state, {pin: Object.assign(state.pin, action.payload.pin)}));
            return Object.assign({}, state, {pin: Object.assign(state.pin, action.payload.pin)});
        default:
            return state;
    }
};

使用 ng2-final AoT：

export function settings (state:SettingsModel = new SettingsModel(), action:Action) {

    switch (action.type) {
        case ActionType.SET_SETTINGS:
            return (action.payload !== null) ? action.payload : new SettingsModel();
        case ActionType.UPDATE_SETTINGS:
            console.log(Object.assign(state, {pin: Object.assign(state.pin, action.payload.pin)}));
            return Object.assign({}, state, {pin: Object.assign(state.pin, action.payload.pin)});
        default:
            return state;
    }
};

对于第二个错误，您需要安装 es6-shim 类型，如下所述： https ://github.com/angular/angular/issues/7033#issuecomment-183249303

您也可以通过以下方式对包 json 中的类型执行此操作：

npm i @types/es6-shim -S
