Question

错误471 - 找不到模块！

这是我要写的模型.T 有数据已经在mysql中。从sequilize开始连接。我删除了所有节点模块并再次尝试，没有任何工作。请提出建议。

module.exports = function（sequelize，dataTypes）{

var calender = sequelize.define("calender",{

     listing_id:DATATYPE.INTEGER,

      listdate:DATATYPE.DATE, 

      available:DATATYPE.TEXT, 

      price:DATATYPE.TEXT

     });

return calender;
};

这是代码

现在这是错误

module.js：471 扔错了; ^

如果你使用Express框架，这个例子可以帮到你很多：

https://github.com/sequelize/express-example/tree/master/models

我一开始也遇到了Sequelize的问题。

特别检查：

models/index.js
models/user.js
routes/index.js

Sequelize模型错误调整以使模型在续集并获得此错误
