我的一个文件导入了。在beta.25中，它返回了正确的对象，但在2.2中它返回undefined和一个疯狂的默认值。
我一直在使用webpack 2.1.0-beta.25并升级到2.2.0版本。我已经降级回2.1.0-beta.28并且工作正常。第二个我切换到2.2.0+，它打破了。
控制台输出版本beta.25：
Object{CENTER: 'CENTER', LEFT: 'LEFT', RIGHT: 'RIGHT'}, Object{Align: Object{CENTER: 'CENTER', LEFT: 'LEFT', RIGHT: 'RIGHT'}, SortingDirection: Object{ASC: 'ASCENDING', DESC: 'DESCENDING'}}
控制台输出版本2.2.0：

导入：
