node.js - Sequelize -cli db :seed returning 'Unhandled rejection TypeError: undefined is not a function'

Question

我正在使用 sequelize-cli (v1.9.1) 并且我正在尝试在运行 db:migration 后进行播种，但是当我运行 db:seed 时我不断收到以下错误消息:

Sequelize [Node: 0.12.7, CLI: 1.9.1, ORM: 3.9.0]

Loaded configuration file "src/server/config/config.json".
Using environment "development".
Using gulpfile /usr/local/lib/node_modules/sequelize-cli/lib/gulpfile.js
Starting 'db:seed'...
Finished 'db:seed' after 96 ms

这是我的种子文件的样子:

'use strict';

module.exports = {
    up: function (queryInterface, Sequelize) {

        /*
         Add altering commands here.
         Return a promise to correctly handle asynchronicity.

         Example:
         return queryInterface.bulkInsert('Person', [{
         name: 'John Doe',
         isBetaMember: false
         }], {});
         */
        return queryInterface.bulkInsert('Users', [{
            id: Sequelize.UUIDV4,
            username: 'someone@email.com',
            email: 'someone@email.com'
        }], {});
    },

    down: function (queryInterface, Sequelize) {
        /*
         Add reverting commands here.
         Return a promise to correctly handle asynchronicity.

         Example:
         return queryInterface.bulkDelete('Person', null, {});
         */
        return queryInterface.bulkDelete('Users', null, {});
    }
};

用

sequelize db:seed:all

并分别为每个对象添加 createdDate {createdAt:'2016-03-31T08:00:10.354Z'} 和 updatedDate{updatedAt:'2016-03-31T08:00:10.354Z'} 。
