Sequelize对象不是一个函数

我正在从这个回购工作，并试图将其转换到PostgreSQL这里是我的错误：

/home/otis/Developer/Shipwrecked/Hatchway/node_modules/sequelize/lib/sequelize.js:601 this.importCache[path] = defineCall(this, DataTypes); ^ TypeError: object is not a function at Sequelize.import (/home/otis/Developer/Shipwrecked/Hatchway/node_modules/sequelize/lib/sequelize.js:601:30) at db.sequelize (/home/otis/Developer/Shipwrecked/Hatchway/models/index.js:15:37) at Array.forEach (native) at Object.<anonymous> (/home/otis/Developer/Shipwrecked/Hatchway/models/index.js:14:6) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.<anonymous> (/home/otis/Developer/Shipwrecked/Hatchway/app.js:10:12) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.<anonymous> (/home/otis/Developer/Shipwrecked/Hatchway/bin/www:7:11) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) 

这是导致错误的代码（models / index.js）：

 var fs = require("fs"); var path = require("path"); var Sequelize = require("sequelize"); var env = process.env.NODE_ENV || "development"; var config = require(__dirname + '/../config.json')[env]; var sequelize = new Sequelize(config.database, config.username, config.password, config); var db = {}; fs .readdirSync(__dirname) .filter(function(file) { return (file.indexOf(".") !== 0) && (file !== "index.js"); }) .forEach(function(file) { var model = sequelize.import(path.join(__dirname, file)); db[model.name] = model; }); Object.keys(db).forEach(function(modelName) { if ("associate" in db[modelName]) { db[modelName].associate(db); } }); db.sequelize = sequelize; db.Sequelize = Sequelize; module.exports = db; 

如果我注释掉以下几行，错误就会停止：

 fs .readdirSync(__dirname) .filter(function(file) { return (file.indexOf(".") !== 0) && (file !== "index.js"); }) .forEach(function(file) { var model = sequelize.import(path.join(__dirname, file)); db[model.name] = model; }); 

Node.js错误是不是我的强项，所以我不知道怎么回事，我也可以发布我的config.json如果需要？

如果我们看一下代码导入 ：

  if (!this.importCache[path]) { var defineCall = (arguments.length > 1 ? arguments[1] : require(path)); this.importCache[path] = defineCall(this, DataTypes); } 

…可以理解，它看起来像一个文件夹与模型有一个文件，是不是一个有效的模型文件，通常是正确的模块。 因此，试图通过“理想的”获取错误来激活它。 检查文件夹模型。
