我正在尝试设置unit testing框架进行反应。 这样做时发生以下错误。 我已经search了所有的互联网没有解决scheme正在工作。 下面是显示的错误和我正在使用的代码/包。

非常感谢帮助!

       

网上收集的解决方案 "Karmaunit testing:模块名称“react”尚未加载上下文:_。 使用require()"

你所描述的错误正是RequireJS在CommonJS表单( require('modX')require调用时给你的,而不是AMD表单( require(['modX'], function (modX) {...}) ), 并且调用完成而不被包装在define 。 RequireJS为使用CommonJS表单提供了一些支持,但开发人员必须完成的工作量极less,以确保其正常工作。 以此开始的脚本将不起作用:

 var modX = require('modX'); // rest of the module 

你得到了你得到的错误信息。 你需要这个:

 define(function (require) { var modX = require('modX'); // rest of the module }); 

你的设置正在进行的是,Babel正在将ES6模块转换成使用require而没有define包装器的东西。 为了让Babel输出适当的AMD模块,您需要安装babel-plugin-transform-es2015-modules-amd并将transform-es2015-modules-amd到您的Babel插件列表中。 请参阅这里的文档。
