【问题描述】：

我想运行我的应用程序，但突然收到此错误。为什么？

这是我工作的订单的样子。

./
├─ app.js
├─ .env
├─ .gitignore
├─ node modules/
│  └─ ...
├─ package.json
├─ package-lock.json
├─ models/
│  └─ advertiser/
│     └─ advertiser_info.js
├─ customer
└─ db/
   └─ advertiser_db.js

app.js：

const express = require("express");
const app = express();

/* ******** Database Connection ********* */
var db = require("./db/advertiser_db");


db.sequelize.sync().then(() => 
    console.log("Database connection successfull");
    app.listen(process.env.PORT, () => 
        console.log("Express listening on " + process.env.PORT);

    )
);

db/advertiser_db.js：

require("dotenv").config();
const Sequelize = require("sequelize");
const sequelize = new Sequelize(`$process.env.DB_NAME`, `$process.env.DB_USERNAME`, `$process.env.DB_PW`, 
    host: `$process.env.DB_HOST`,
    dialect: "postgres"
);

const db = ;

db.n_advertiser = sequelize.import(__dirname + "/models/advertiser/advertiser_info.js");
db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

模型/广告商/advertiser_info.js：

module.exports = (sequelize, Sequelize) => 
    return sequelize.define("advertiser", 
        blabla: 
            type: Sequelize.STRING,
            allowNull: false,
        ,
        blabla: 
            type: Sequelize.STRING,
            allowNull: false,
        ,
        email: 
            type: Sequelize.STRING,
            allowNull: false,
            validate: 
                isEmail: true
            
        ,
        hashedPw: 
            type: Sequelize.STRING,
            allowNull: false
        ,
        blabla: 
            type: Sequelize.STRING,
            allowNull: false,
        ,
        blabla: 
            type: Sequelize.STRING,
            allowNull: false
        ,
        blabla: 
            type: Sequelize.BOOLEAN,
            allowNull: false,
            defaultValue: true,

        
    )

如果我运行 app.js 文件，我会看到以下错误：

internal/modules/cjs/loader.js:969
  throw err;
  ^

    '/Users/yildirim/Desktop/nn_backend/app.js'
  ]

我看到它向我展示了一条根本不存在的路径。为什么？我从未定义过该路径： '/Users/yildirim/Desktop/nn_backend/db/models/advertiser/advertiser_info.js'

感谢您的有用回答。

【问题讨论】：

你安装了 sequelize.js 吗？

@RatnadeepBhattacharyya 是的，我做到了

我认为这里的问题是无法从该位置访问模块目录，请尝试使用更高的权限。

【参考方案1】：

尝试从原始文件夹再次打开您的文件。更改位置后，我遇到了同样的问题。
