Sequelize 错误:在 Index.js 中未定义 defineCall

2022-01-19 00:00:00 node.js express mysql sequelize.js

我一直收到此续集错误

/node_modules/sequelize/lib/sequelize.js:508
      this.importCache[path] = defineCall(this, DataTypes);
                           ^
    TypeError: defineCall is not a function
    at module.exports.Sequelize.import             (/node_modules/sequelize/lib/sequelize.js:508:32)
at   /models/Index.js:16:33

at Function.Module._load (module.js:300:12)
at Module.require (module.js:353:17)
at require (internal/module.js:12:17)

我已将范围缩小到下面的 Index.js 文件中的注释代码

I've narrowed it down to the commented code in my Index.js file below

使用严格"；

var fs        = require("fs");
var path      = require("path");
var Sequelize = require("sequelize");
var config    = require(path.join(__dirname, '..', 'config',    '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");
  })

下面这段注释的代码破坏了它<代码>//.forEach(函数(文件){//var model = sequelize.import(path.join(__dirname, file));//db[model.name] = 模型；//});

This commented code below breaks it //.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;

有谁知道为什么会出现这个错误?

Does anyone know why this error is occuring?

推荐答案

这通常意味着您正在尝试导入非 sequelize 对象.如果您的索引文件的名称是 Index.js 那么您需要在过滤器函数中更改它(第一个字母是大写)

This usually means you're trying to import a non-sequelize object. If the name of your index file is Index.js then you need to change it in your filter function (first letter is capital)

return (file.indexOf(".") !== 0) && (file !== "Index.js");

因为它区分大小写.还要检查您的导入文件夹中是否没有任何其他未定义续集模型的文件.如果只是将它们添加到您的过滤器功能中.

As it is case sensitive. Also check that there aren't any other files in your import folder which don't define sequelize model. If there are just add them to your filter function.
