MERN堆栈-找不到模块-module.exports=mongoose.model

Question

我正在学习这篇MERN堆栈教程，并从第7分钟开始观看这段关于模型和模式的视频：https://www.youtube.com/watch?v=O8IipcpTmYU&list=PL4cUxeGkcC9iJ_KkrkBZWZRHVwnzLIoUE&索引=5

我用mongoose创建了一个模式，并导出了它，当需要它时，在我的路由文件中找不到它。

文件结构：

MERN
| client/
| models/
|  - workoutModel.js
| server/
|  - node_modules/
|  - routes/
|  -- workouts.js
|  - .env
|  - package-lock.json
|  - package.json
|  - server.js

训练.js

const express = require('express');
const router = express.Router();
const Workout = require('../models/workoutModel.js');
// /api/workouts/
// GET all workouts
router.get('/', (req, res) => {
res.json({msg: 'GET all workouts'})
})
// GET single workout
router.get('/:id', (req, res) => {
res.json({msg: 'GET single workout'})
})
// POST new workout
router.post('/', async (req, res) => {

})
// DELETE a workout
router.delete('/:id', (req, res) => {
res.json({msg: 'DELETE a workout'})
})
// UPDATE a workout
router.patch('/:id', (req, res) => {
res.json({msg: 'UPDATE a workout'})
})
module.exports = router;

workoutModel.js

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const workoutSchema = new Schema({
title: {
type: String,
required: true
},
reps: {
type: Number,
required: true
},
load: {
type: Number,
required: true
}
}, { timestamps: true });
module.exports = mongoose.model('Workout', workoutSchema);

这是我的错误：

throw err;

}

我逐字逐句地遵循了教程，我不知道哪里出了问题！感谢您的帮助。

Answer 1

也许这个代码会像这个

const Workout = require('../../models/workoutModel.js');

你应该再次检查文件路径

Answer 2

你能用这行试试吗？

const Workout = require('../models/workoutModel');
