在运行react-native start
出现一下错误
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

有可能是没有安装watchman
, 或者更新mac OS后没有更新watchman
执行一下以下命令安装watchman
即可
brew install watchman
