npm run dev 報錯

1.install警告：  可忽略

 npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents):
 npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

 

2.  vue-loader  安裝"vue-loader": "11.1.4",可解決

node build/dev-server.js

> Starting dev server...

3.   端口占用 : 改配置端口 或 kill當前已佔用端口的進程

events.js:141

     throw er; // Unhandled 'error' event

     ^
