Benim yapılandırma şartname aşağıdaki gibi:

Node version:v4.3.0
NPM version:3.7.3

Bunu düzeltmek için herhangi bir yardım çok takdir edilecektir, yüklü karma sürümü elde edemiyorum, makinemde düzgün yüklenmemiş olduğunu düşünüyorum.

Bu bir hata değil. Mac OS özelliğine sahip fseventsd'un Linux'a yüklenemediğine dair bir uyarıdır.

Orada paniğe gerek yoktur ve fsevents çalışmaya devam eder ihtiyacı paketi - Bu isteğe bağlı bir bağımlılık var bu yüzden. Birçok kişi (bu gerçek hata değil, bir uyarı olarak kullanılan özellikle beri) bu konuda karıştı

beri bunun için an open bug to make the current warning into an INFO instead
