Help is greatly appreciated!非常感谢帮助!
The error you describe is exactly what RequireJS gives you when you have a require
call in the CommonJS form ( require('modX')
) instead of the AMD form ( require(['modX'], function (modX) {...})
), and the call is done without being wrapped in define
.您所描述的错误正是RequireJS给你当你有一个
require
在CommonJS的形式调用( require('modX')
而不是AMD的形式( require(['modX'], function (modX) {...})
),并且调用完成时没有被包裹在define
。 RequireJS provides some support for using the CommonJS form, but there is a minimum of work that must be done by the developer to ensure that it works. RequireJS 为使用 CommonJS 表单提供了一些支持,但开发人员必须完成最少的工作以确保其工作。 A script that starts with this won't work:
以此开头的脚本将不起作用:
var modX = require('modX');
// rest of the module
You get the error message you got.您会收到您收到的错误消息。 You need this instead:
你需要这个:
define(function (require) {
var modX = require('modX');
// rest of the module
});
What is going on with your setup is that, as it is, Babel is transforming the ES6 modules into something that uses require
without the define
wrapper.您的设置正在发生的事情是,事实上,Babel 正在将 ES6 模块转换为使用
require
而不使用define
包装器的东西。 In order to get Babel to output proper AMD modules, you need to install babel-plugin-transform-es2015-modules-amd
and add transform-es2015-modules-amd
to your list of Babel plugins.为了让 Babel 输出正确的 AMD 模块,你需要安装
babel-plugin-transform-es2015-modules-amd
并将transform-es2015-modules-amd
到你的 Babel 插件列表中。 See the documentation here .请参阅 此处的文档。
