按照vue官网上的安装流程，新建的项目跑不起来，为嘛？

Question

1、按照如vue官网上如下步骤建的：

# 全局安装 vue-cli

$ npm install --global vue-cli

# 创建一个基于 webpack 模板的新项目

$ vue init webpack my-project

# 安装依赖，走你

$ cd my-project

$ npm install

$ npm run dev

最后运行 npm run dev 项目竟然起不来

错误如下：

D:\study\my-project>npm run dev

> vue-web@1.0.0 dev D:\study\my-project

> node build/dev-server.js

> Starting dev server...

events.js:182

2、node版本 v8.1.4   npm 版本5.0.3

      node版本v6.11.1的也试过，也跑不起来

Answer 1

看上面的错误， 运行到服务时-->出现错误Error: listen EADDRINUSE :::8080是不是端口占用，换一个
