mac 系统 执行 sudo npm run dev

first-vue@1.0.0 dev /Users/xxx//WebstormProjects/first-vue

> node build/dev-server.js

events.js:160

      throw er; // Unhandled 'error' event

npm ERR! Make sure you have the latest version of node.js and npm installed.

npm ERR! If you do, this is most likely a problem with the first-vue package,

npm ERR! not with npm itself.

npm ERR! Tell the author that this fails on your system:

npm ERR!     node build/dev-server.js

npm ERR! You can get information on how to open an issue for this project with:

npm ERR!     npm bugs first-vue

npm ERR! Or if that isn't available, you can get their info via:

npm ERR!     npm owner ls first-vue

npm ERR! There is likely additional logging output above.

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

该问题是因为脚手架工具默认监听的是8080端口，此时是8080端口被占用情况导致的。

找出8080端口占用进程然后杀死

执行sudo lsof -i :8080

COMMAND PID  USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME

httpd    79  root    6u  IPv6 0x16935b8002e27567      0t0  TCP *:http-alt (LISTEN)

执行sudo kill -9 79 

再执行sudo npm run dev,然后搭建成功.
