angularjs - Peringatan Webpack di Windows - Ada modul lain dengan nama yang sama jika huruf besar-kecil diabaikan

Saat saya menjalankan demo di Windows10 X64 dari https://angular.io/docs/ts/latest/guide/webpack.html, saya mendapatkan sejumlah besar peringatan. misalnya:

WARNING in ./~/.npminstall/rxjs/5.0.0-beta.6/rxjs/Notification.js
There is another module with an equal name when case is ignored.
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.
