Problemas com JWT-Decode

Pessoal estou tentando dar continuidade ao curso mas esse problema está travando a aplicação, segue a mensagem de erro: Could not find a declaration file for module 'jwt-decode' ... implicitly has an 'any' type. Try npm i --save-dev @types/jwt-decode if it exists or add a new declaration (.d.ts) file containing declare module 'jwt-decode';

Ja fiz o npm install jwt-decode e npm install --save-dev @types/jwt-decode, mas não está corrigindo.

segue user.service.ts:

  import { Injectable } from '@angular/core';
  import { Observable, Subject } from 'rxjs';
  import { TokenService } from '../token/token.service';
  import { User } from './user';
  import jwt_decode from 'jwt-decode';

  @Injectable({
    providedIn: 'root'
  })
  export class UserService{

    private userSubject: Subject<User> = new Subject<User>();
    constructor(private tokenService: TokenService){

      this.tokenService.hasToken() &&
      this.decodeAndNotify();
    }

    setToken(token:string) :void{
      this.tokenService.setToken(token);
      this.decodeAndNotify();
    }

    private decodeAndNotify(): void{
      const token = this.tokenService.getToken();
      const user:User = jwt_decode(token) as User;
      this.userSubject.next(user);
    }

    getUser(): Observable<User>{
      return this.userSubject.asObservable();
    }
  }
