There is another module with an equal name when case is ignored？

使用angular2+webpack开发项目，在mac上运行没有问题，但是在windows上启动报了很多warning，导致项目启动不起来。

已将项目原型上传至github： https://github.com/zhouweimin...

在windows上运行时，报错：

WARNING in ./~/.npminstall/rxjs/5.0.0-beta.6/rxjs/Notification.js

This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Rename module if multiple modules are expected or use equal casing if one module is expected.

尝试过很多修改，github上也有类似的提问，但貌似没能解决，也测试使用 https://github.com/Urthen/cas...，但是都没能解决。

求大神帮忙！
