com.github.facebook.watchman.plist用於編寫：權限被拒絕運行反應本機初始項目

Question

我正在學習react-native.And並遵循網站上的教程。當我執行「react-native run-ios 」。它發生了一些錯誤消息。

Looking for JS files in 
    /Users/Mapple/Developer/React-native-workspace/HelloWorld 

[19:16:32] <START> Building Dependency Graph 
[19:16:32] <START> Crawling File System 
[Hot Module Replacement] Server listening on /hot 

React packager ready.

我發現根本沒有文件com.github.facebook.watchman.plist在/用戶/馬普爾/庫/ LaunchAgents。我嘗試了各種方法，但它並沒有起到作用
我會瘋

包版本：。

1.node：V6.1.0
2.watchman：4.6.0
