"amdefine" 无法加载自定义模块

Question

我安装了 requirejs 包来优化文件路径的工作。一般来说，我会执行以下步骤：

我有一个带有文件路径的对象，它有下一个值：

"app/database": "/home/dmitry/projects/information-platform-api/app/utils/database"

在 app.js（主文件）中初始化 requirejs 映射后：

requirejs.config({
    baseUrl: __dirname,
    nodeRequire: require,
    paths: paths,
    map: {
        '*': paths
    }
});

之后，我需要初始化基础模型，并在 for 的帮助下调用了 paths 对象中的所有文件。这看起来像：

for (let file in paths) {
    requirejs(paths[file]);
}

当我初始化具有上述"app/database"依赖关系的文件时，出现消息错误：Error: Cannot find module 'app/database'.

也许，我不明白 "How works the amdefine"，但我有意见，requirejs 和 amdefine 不 link。你有什么想法，为什么它不起作用？

文件的一部分，需要调查：

if (typeof define !== 'function') {
    var define = require('amdefine')(module);
}

define([
    'sequelize',
    'app/database',
    'model/student'
], (
    Sequelize,
    sequelize,
    Student
) => { });

我的调查结果：

amdefine 不知道 requirejs 映射。

伙计们，解决方案就在这里。 amdefine有两个参数，第一个参数是一个全局变量module，第二个是require调用本地文件的函数。默认情况下，它只是 require 而不是 requirejs 包含自定义映射。

if (typeof define !== 'function') {
    var define = require('amdefine')(module, require('requirejs'));
}

"amdefine" 无法加载自定义模块

The "amdefine" can not load a custom module

node.js

requirejs

amdefine

requirejs-define
