“从facebook / react-native / Examples运行示例时，”观察更改文件时出错：EMFILE“

Question

I want to run the Examples from facebook/react-native/Examples in OS X 10.12.

First I use npm install and then use npm start :

There is an error:

Error watching file for changes: EMFILE
{"code":"EMFILE","errno":"EMFILE","syscall":"Error watching file for changes:","filename":null}
Error: Error watching file for changes: EMFILE
    at exports._errnoException (util.js:1008:11)
    at FSEvent.FSWatcher._handle.onchange (fs.js:1406:11)

Then I use Xcode run the code but there is the same error.

I need help or advice. Thanks very much.
