【问题描述】：

我正在关注关于 sequelize-cli 的教程：https://andela.com/insights/using-graphql-and-sequelize/

我得到一个错误：'sequelize.import 不是一个函数'

它来自 models/index.js（应该捆绑所有模型）

'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 = ; 

// Set DB Connection
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);


// Import model files in models folder and make table associations where present
fs
  .readdirSync(__dirname)
  .filter(file => 
    return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
  )
  .forEach(file => 
    const model = sequelize['import'](path.join(__dirname, file));
    db[model.name] = model;
  );

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

db.sequelize = sequelize;

我在网上搜索解决方案，但我看到的都不起作用。

有什么想法吗？？

【参考方案1】：

好的解决了！

没想到

  .forEach(file => 
    const model = sequelize['import'](path.join(__dirname, file));
    db[model.name] = model;
  );

在同一个位置，所以正确答案是：

  .forEach(file => 
    db[model.name] = file
  );
