当您require以Commonjs形式（require(’modX’)）而不是AMD形式（require([’modX’], function(modX) {...})）进行调用时，您所描述的错误正是RequireJS给您的， 调用没有被封装进来define。RequireJS为使用Commonjs表单提供了一些支持，但是开发人员必须做最少的工作才能确保它能正常工作。以此开头的脚本将不起作用：
var modX = require(’modX’);// rest of the module
您收到错误消息。您需要此：
define(function (require) { var modX = require(’modX’); // rest of the module});
设置的实际情况是，Babel正在将ES6模块转换为require无需define包装即可使用的模块。为了使Babel输出正确的AMD模块，您需要安装babel-plugin-transform-es2015-modules-amd并添加transform-es2015-modules-amd到Babel插件列表中。请参阅此处的文档。
解决方法我正在尝试建立反应的单元测试框架。这样做时，发生以下错误。我搜索了整个互联网，但没有有效的解决方案。下面是显示的错误和我正在使用的代码/软件包。
