找不到模块：内部/模块/cjs/loader.js:969

Question

我想运行我的应用程序，但突然收到此错误。 为什么？

这就是我工作的订单的样子。

• 应用程序.js
• .env
• .gitignore
• 节点模块
  • /...
• package.json
• 封装锁.json
• 楷模
  • 广告商
    • 广告商信息.js
• 顾客
• D b
  • 广告商_db.js

应用程序.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/db/advertiser_db.js',
    '/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'

感谢您提供有用的答案。

尝试从原始文件夹再次打开您的文件。 我有同样的问题，现在它已经修复了，在更改位置后。
