属性'ngRedux‘在’AppModule‘类型上不存在。？

Question

我一直在angular6中实现redux，它几乎完成了应用程序的工作，但是它在节点cli 属性'ngRedux‘不存在于'AppModule'.?类型时抛出了一个错误。

当我在NgRedux导入和导出中添加App.module.ts时，它会抛出一个错误，然后应用程序停止工作。

有什么解决办法吗？

我的app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { NgRedux, NgReduxModule } from '@angular-redux/store';
import { AppComponent } from './app.component';
import { MatButtonModule } from '@angular/material/button';
import { HomeComponent } from './home/home.component';
import { ProfileComponent } from './profile/profile.component';
import { MatInputModule } from '@angular/material/input';
import { MatCardModule } from '@angular/material/card';
import { MatBadgeModule } from '@angular/material/badge';

import { createLogger } from 'redux-logger';

import { IAppState, rootReducer, INITIAL_STATE } from './reducers/rootReducers';


@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    ProfileComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    NgReduxModule,
    MatButtonModule,
    MatInputModule,
    MatCardModule,
    MatBadgeModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { 

      constructor(ngRedux: NgRedux<IAppState>) {
      // ngRedux.configureStore(rootReducer, INITIAL_STATE);
      this.ngRedux = ngRedux;
      ngRedux.configureStore(rootReducer, INITIAL_STATE, [ createLogger() ]);
      console.log(this.ngRedux.getState());
    }
}

问题是当您使用this.ngRedux时，ngRedux没有被声明为AppModule类的变量。移除this或声明为类变量，如下所示：

export class AppModule { 
ngRedux : NgRedux;
  constructor(ngRedux: NgRedux<IAppState>) {
    // ngRedux.configureStore(rootReducer, INITIAL_STATE);
    this.ngRedux = ngRedux;
    ngRedux.configureStore(rootReducer, INITIAL_STATE, [ createLogger() ]);
    console.log(this.ngRedux.getState());
  }

}
