npm ERR! You can get information on how to open an issue for this project with:
npm ERR!     npm bugs mdns
npm ERR! Or if that isn't available, you can get their info via:
npm ERR!     npm owner ls mdns
npm ERR! There is likely additional logging output above.

npm ERR! Please include the following file with any support request:

重新npm install,重新安装也不行；
解决：
是换了个linux服务器原因，需要sudo apt-get install libavahi-compat-libdnssd-dev,Debian系统。
