Angular 标识符'；长度'；没有定义'；空'；不包含此类成员ng

我正在尝试创建一个简单的TODO应用程序，我正在使用

ng2 redux

进行状态管理，我正在尝试访问视图中的

TODO

数组长度 虽然应用程序编译成功，但我的代码中仍显示一个错误

错误：

当前代码：

待办事项仪表板.component.ts

import { Component, OnInit } from '@angular/core';
import { NgRedux, select } from 'ng2-redux';
import { IAppState } from 'src/store';
@Component({
  selector: 'app-todo-dashboard',
  templateUrl: './todo-dashboard.component.html',
  styleUrls: ['./todo-dashboard.component.css'],
})
export class TodoDashboardComponent {
  @select() todos;
  constructor(private ngRedux: NgRedux<IAppState>) {}
}

export interface IAppState {
  todos: any[];
  lastUpdated: Date;
}

export const INITIAL_STATE: IAppState = {
  todos: [],
  lastUpdated: null,
};

export const rootReducer = (state: IAppState, action): IAppState => {}

我曾尝试在

tsconfig.json

文件中添加

“strictNullChecks”：false

，但运气不佳，因此如果有人能帮我禁用错误或克服错误，我将不胜感激：）

export interface IAppState {
  todos: any[];
  lastUpdated: Date;
}

export const INITIAL_STATE: IAppState = {
  todos: [],
  lastUpdated: null,
};

export const rootReducer = (state: IAppState, action): IAppState => {}
