kibana启动报错 Failed to watch files

问题

npm start启动 kibana 时，莫名其妙报错：

看报错信息也看不出来为什么，甚至试过重启虚拟机.....

解决办法

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

The system has a limit to how many files can be watched by a user. You can run out of watches pretty quickly if you have Grunt running with other programs like Dropbox.
