Question

一切正常，直到我开始在app.module中添加组件。我有2个文件夹，一个连接到数据库（Mongodb）的后端和一个用于查看项目的前端。当我运行后端时，它会连接，但是当我运行前端时，它会给我这个错误：

"ERROR in ../node_modules/@auth0/angular-jwt/index.d.ts(1,47): error TS2307: 
Cannot find module '@angular/core'.
../node_modules/@auth0/angular-jwt/src/jwt.interceptor.d.ts(1,70): error 
TS2307: Cannot find module '@angular/common/http'.
../node_modules/@auth0/angular-jwt/src/jwt.interceptor.d.ts(3,28): error 
TS2307: Cannot find module 'rxjs/internal/Observable'.
../node_modules/@auth0/angular-jwt/src/jwtoptions.token.d.ts(1,32): error 
TS2307: Cannot find module '@angular/core'."

我的代码在下面。

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { ApiService } from './api.service';
import {MatButtonModule, MatToolbarModule, MatInputModule} from '@angular/material';


import {BrowserAnimationsModule, NoopAnimationsModule} from '@angular/platform-browser/animations';
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
import {MatListModule} from '@angular/material/list';

import { RegisterComponent } from './register/register.component';
import { LoginComponent } from './login/login.component';
import { MessageComponent } from './messages/message.component';
import { AboutusComponent } from './aboutus/aboutus.component';
import {AddnewsComponent} from './addnews/addnews.component';
import {NewsListComponent} from './newslist/newslist.component';
import {ViewComponent} from './view/view.component';
@NgModule({
  declarations: [
    AppComponent, MessageComponent, RegisterComponent, LoginComponent,AboutusComponent,AddnewsComponent,NewsListComponent,ViewComponent
 ],
imports: [
  BrowserModule, HttpClientModule, FormsModule, ReactiveFormsModule,  MatButtonModule, MatInputModule, MatToolbarModule,  BrowserAnimationsModule,
 NoopAnimationsModule, MatListModule, RouterModule.forRoot(
   [
    {path: 'addnews', component:AddnewsComponent},
    {path: 'aboutus', component: AboutusComponent},
    {path: 'newslist',component: NewsListComponent},
    {path: 'view', component: ViewComponent},
    {path: 'register', component: RegisterComponent},
   {path: 'login', component: LoginComponent},
   {path: 'messages', component: MessageComponent} 
  ]
)
],
providers: [ApiService],
bootstrap: [AppComponent]
 } )
 export class AppModule { }

这取决于已将哪些依赖项添加到组件。另外，您是否要导入@ auth0 / angular-jwt所需的angular公共模块？ It's peer dependencies要求角度共通-
