如何修复 NestJS 项目结构中导入的相对路径？

Question

I'm following the article and I'm struggling with imports on the step with creating UserService :

import { Injectable } from '@nestjs/common';
import { InjectRepository } from "@nestjs/typeorm"; 
import { UserDto } from 'src/user/dto/user.dto'; 
import { Repository } from "typeorm"; 
import { UserEntity } from './../../entity/user.entity';

@Injectable()
export class UserService { 

constructor( 
@InjectRepository(UserEntity) private userRepository: Repository<UserEntity> 
}{}
 
create(user: UserDto): Promise<UserDto> {
   return this.userRepository.save(user); 
 }
 findAll(): Promise<UserDto[]> {
   return this.userRepository.find(); 
 } 
}

The problem is for lines:

import { UserDto } from 'src/user/dto/user.dto';

and specifically:

import { UserEntity } from './../../entity/user.entity';

Does anyone know what can be the cause of this problem? What can I fix from my side?

UserDTO:

import { IsNumber, IsString } from 'class-validator';
export class UserDto { 
@IsNumber() id: number;
@IsString() name: string;
@IsString() lastName: string; 
}

UserEntity :

import { Column, Entity, PrimaryGeneratedColumn } from 'typeorm';
@Entity() 
export class UserEntity { 

@PrimaryGeneratedColumn() 
id: number;

@Column({ nullable: false }) 
name: string;

@Column({ name: 'last_name', nullable: false }) 
lastName: string; 
}

In the project of the given article, by the same principle :

there are no any issues, but from my side I see errors related to the project imports.

Am I missing something? Do I need to add the absoluth path instead of relative?

There's the full project structure .

I'm ready to provide more details if it helps to detect and fix the issue.

Thank you in advance.

Dots inside folder names are generally not a good idea. And try

import { UserEntity } from './../../entity/user.entity/user.entity';

or even in a shorter way as:

import { UserEntity } from '../../entity/user.entity/user.entity';

and accordingly:

import { UserDto } from '../../dto/user.dto/user.dto';
