Question

我是nodejs的新手，尝试通过浏览指南来制作API，但遇到了一个问题，即使使用google tho也无法解决。这是我的命令行文字。

consign v0.1.2 Initialized in d:\Jinn\API

+ .\db.js
+ .\libs\middlewares.js

+ .\routes\tasks.js

    sequelize = new _sequelize2.default(config.database, config.username, config
.password, config.params);
              ^

似乎麻烦在db.js文件中的某处，所以这里是代码：

import fs from "fs";
import path from "path";
import Sequelize from "sequelize";

let db = null;

module.exports = app => {
  if (!db) {
    const config = app.libs.config;
    sequelize = new Sequelize(
      config.database,
      config.username,
      config.password,
      config.params
    );

    db = {
     sequelize,
     Sequelize,
     models: {}
    };

    // Загрузка моделей
    const dir = path.join(__dirname, "models");
    fs.readdirSync(dir).forEach(file => {
      const modelDir = path.join(dir, file);
      const model = sequelize.import(modelDir);
      db.models[model.name] = model;
    });

    Object.keys(db.models).forEach(key => {
      db.models[key].associate(db.models);
    });
  }

  return db;
};

说实话，我大部分都遵循说明和复制粘贴的代码片段，这就是为什么我感到沮丧，因为它应该有用。有什么想法吗？

没有定义sequelize（nodejs）
