错误：“未捕获（承诺）：错误：无法匹配任何路由。URL段：'auth / facebook'”

Question

]我正在尝试使用Node.js和护照将Facebook登录集成到我的MEAN堆栈应用程序中，但出现以下错误。

我的passport.js和注册component.html位于两个不同的文件夹中。我没有解决该问题的方法。

下面是我的password.js

var FacebookStrategy = require('passport-facebook').Strategy;
var User =require('../models/User')
var session=require('express-session');
module.exports=function(app,passport){

app.use(passport.initialize());
app.use(passport.session());
app.use(session({secret: 'keyboard cat',resave: false,saveUninitialized: 
 true,cookie: { secure: false }}))


passport.serializeUser(function(user, done) {
done(null, user.id);
 });

passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
  done(err, user);
 });
 });


   passport.use(new FacebookStrategy({
   clientID: '456240351574071',
   clientSecret: '0e8668a1e117c3488787bfd73de693e3',
   callbackURL: "http://localhost:8080/auth/facebook/callback",
   profileFields: ['id', 'displayName', 'photos', 'email']
    },
   function(accessToken, refreshToken, profile, done) {
   console.log(profile);
  //User.findOrCreate(..., function(err, user) {
  // if (err) { return done(err); }
    done(null, profile);
  //});
   }
   ));
  app.get('/auth/facebook/callback', passport.authenticate('facebook', { 
   failureRedirect: '/login' }));
  app.get('/auth/facebook', passport.authenticate('facebook', { scope: 
  'email' }));
   return passport;
    }

下面是我的注册组件。html

<mat-card class="example-card">
  <mat-card-header>
    <mat-card-title>REGISTER</mat-card-title>
      </mat-card-header>
    <mat-card-content>
     <form class="example-form">
       <table class="example-full-width" cellspacing="0">
        <tr>
         <td>
           <mat-form-field class="example-full-width">
         <input matInput placeholder="Name" [(ngModel)]="name" name="name" 
        required>
         </mat-form-field>
       </td>
     </tr>
     <tr>
     <td><mat-form-field class="example-full-width">
       <input matInput placeholder="EmailAddress" 
     [(ngModel)]="emailAddress" name="emailAddress" required>
     </mat-form-field></td>
   </tr>
   <tr>
     <td>
   <mat-radio-group>
   <mat-radio-button value="1">Male</mat-radio-button>
    <mat-radio-button value="2">Female</mat-radio-button>
    </mat-radio-group>
     </td>
     </tr>
    <tr>
     <td><mat-form-field class="example-full-width">
       <input matInput placeholder="Password" [(ngModel)]="password" 
        type="password" name="password" required>
     </mat-form-field></td>
       </tr>

      </table>
     </form>
    <mat-spinner [style.display]="showSpinner ? 'block' : 'none'"></mat- 
        spinner>
   </mat-card-content>
      <mat-card-actions>
     <button mat-raised-button (click)="signUp()" color="primary">Sign 
      Up</button>
        <a href="/auth/facebook" target="_blank"><button type="button" 
       class="btn btn-success"> Facebook </button></a>
         <button mat-raised-button (click)="socialSignIn('google')" 
          color="primary">Sign in with Google</button>
         </mat-card-actions>
                 </mat-card>

和以下是我在控制台中遇到的错误： core.js：1673错误错误：未捕获（承诺）：错误：无法匹配任何路由。网址区隔：“ auth / facebook” 错误：无法匹配任何路线。网址段：“ auth / facebook”
