属性 'ngRedux' 在类型 'AppModule' 上不存在。？

Question

我一直在努力在angular6中实现redux，它几乎完成应用程序工作正常，但它在节点cli中抛出错误属性 'ngRedux'没有存在于类型 'AppModule'.?

When i add NgRedux in App.module.ts imports, and exports, It throws an error and application stopped working.

有没有解决办法？

My 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());
    }
}

问题出在您使用 this.ngRedux 时，因为 ngRedux 未声明为 class AppModule 的变量。删除 this 或声明为 class 变量，如：

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());
  }

}
