在 Angular 7 中實現 redux 會出現錯誤 TS2307：找不到模塊“redux”。 錯誤

Question

我正在學習 Redux，我正在嘗試使用 ng2-redux 在 Angular 7 中實現它。 我看到它在 npm 頁面上被棄用，所以我使用建議的npm install @angular-redux/store'安裝它。 我配置了我的 app.module，它給了我這個錯誤： error TS2307: Cannot find module 'redux'. 我是不是導入錯了，可能是什么原因造成的？ 我嘗試在互聯網上搜索，但沒有找到任何東西。 這是我的app.module文件：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { NgRedux, NgReduxModule } from '@angular-redux/store'
import { rootReducer, AppState } from '../app/store';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
  ],
  providers: [],
  bootstrap: [AppComponent]
})

export class AppModule { 
  constructor(ngRedux: NgRedux<AppState>) {
    ngRedux.configureStore(rootReducer,  {});
  }
}

我的 package.json：
