node.js - 我无法通过 sequelize 进行基本的 sql 查询

Question

我错过了一些东西，我认为这很简单，但我很挣扎。我关注了一个博客，让 OAuth2.0 与 Node 和 Sequelize 与 Postgres 一起工作。有用...
现在我只是想添加一个基本的 SQL 选择，但我无法让它工作。有人可以帮帮我吗？
模型/index.js

'use strict';

const fs = require('fs');
const path = require('path');
const Sequelize = require('sequelize');
const basename = path.basename(__filename);
const env = process.env.NODE_ENV || 'development';
const config = require(__dirname + '/../config/config.json')[env];
const db = {};

let sequelize;
if (config.use_env_variable) {
  sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
  sequelize = new Sequelize(config.database, config.username, config.password, config);
}

fs
  .readdirSync(__dirname)
  .filter(file => {
    return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
  })
  .forEach(file => {
    const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
    db[model.name] = model;
  });

Object.keys(db).forEach(modelName => {
  if (db[modelName].associate) {
    db[modelName].associate(db);
  }
});

db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

Controller / Controller .js

const bcrypt = require('bcrypt');
const OAuthTokensModel = require('../models').OAuthTokens;
const OAuthClientsModel = require('../models').OAuthClients;
const OAuthUsersModel = require('../models').OAuthUsers;
const db = require('../models').db;

module.exports.change = function () {
    return db.sequelize.query(`
        SELECT * FROM "OAuthUsers"
        `,
        {
            type: sequelize.QueryTypes.SELECT
        }
        )
        .catch((error) => console.error(error));
};

module.exports.getAccessToken = function (bearerToken) {
    return OAuthTokensModel.findOne(
        {
            where: {
                accessToken: bearerToken
            },...

我返回以下错误:
无法读取未定义的属性“Sequelize ”
正如我所说，我确定这很简单，但我是 Sequelize 新手。

尝试将 sequelize 导入您的 Controller
const sequelize = require('sequelize');
