npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\fsevents):

原因:fsevents不在package.json里，但是仍然安裝了，是因為你的系統不是Windows系統，fsevents是蘋果系統的可選依賴,你的項目有可能是團隊項目，別人在他的mac上安裝了fsevents相關依賴庫，所以到這邊你也就安裝到你的windows上邊了。你可以檢查你的package.json 文件中是不是有fsevents相關依賴，刪除即好！
* 如果沒有，刪除node_modules文件夾，重新安裝各項依賴就好了
* 解決:fsevent是mac osx系統的，你是在win或者Linux下使用了 所以會有警告，忽略即可
