node.js / Express服務器在請求時崩潰

Question

我剛剛用express-generator生成了一個服務器。 當我啟動服務器並給出第一個請求時，出現此錯誤。

23 error Or if that isn't available, you can get their info via:
23 error     npm owner ls sevn
23 error There is likely additional logging output above.
24 verbose exit [ 1, true ]

怎么了？ 在哪里可以開始調試？

順便說一句，我有Node.js版本v4.2.4和npm v.3.5.2

謝謝！

編輯：我得到304狀態，我不應該得到200嗎？

問題是我沒有安裝用於快遞服務器的指南針。

解決問題的方法：

gem install compass
