Question

我是Angular8的新手，我正在使用jwthelper编码jwt令牌并提取细节。我需要在我的angular 8项目中实现JwtModule。我正在Angular8的app.module.ts中导入JwtModule。如果我运行ng serve，则会收到上述错误。

ERROR Error: StaticInjectorError(AppModule)[Config]:

请提出解决方案。

本地存储中有一个令牌：

这是我的app.module.ts：

//This is my app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform- 
browser/animations';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';
import { HttpModule } from '@angular/http';
import { JwtModule , JWT_OPTIONS , JwtModuleOptions , 
JwtHelperService} from '@auth0/angular-jwt';
//routing
import { AppRoutingModule } from './app-routing.module';
//components
import { AppComponent } from './app.component';
//modules
import { PortalModule } from './portal/portal.module';
import { LandingPageModule } from './landing-page/landing- 
page.module';
import { NbThemeModule, NbLayoutModule } from '@nebular/theme';
import { NbEvaIconsModule } from '@nebular/eva-icons';
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
//services
import { AuthService } from '../app/services/auth/auth.service';
import { GlobalsService } from  '../app/services/globals.service';
import { UsersComponent } from './users/users.component';
import { SharedModule } from './shared/shared.module';
const JWT_Module_Options: JwtModuleOptions = {
   config: {
   tokenGetter: tokenGetter,
   whitelistedDomains: []
   }
};
@NgModule({
declarations: [
AppComponent,
UsersComponent,
  ],
imports: [
   BrowserModule,
   BrowserAnimationsModule,
   HttpClientModule,
   HttpModule,
   FormsModule,
   ReactiveFormsModule,
   AppRoutingModule,
   PortalModule.forRoot(),
   LandingPageModule,
   NbThemeModule.forRoot({ name: 'default' }),
   NbLayoutModule,
   NbEvaIconsModule,
   SharedModule,
   JwtModule.forRoot(JWT_Module_Options)    
   ],
   providers: [
     AuthService,
     GlobalsService,
     JwtHelperService
     ],

  bootstrap: [AppComponent]
   })
  export class AppModule { }
  export function tokenGetter() {
       return localStorage.getItem("access_token");
  }

StaticInjectorError（平台：核心）[Config]：NullInjectorError：没有Config的提供者！ NullInjectorError：StaticInjectorError（AppModule）[Config]：
