解决方案：

网上找很多帖子，都没有写解决办法，自己来喽，也是神奇的错误

最后，神奇的是，错误居然被哦改好了

解决办法

进入 vue-demo/config/index.js

dev: {

    env: require('./dev.env'),

    port: 8088,        # 注意了啊。。。修改成你要的端口，接着运行代码就看到效果了

    assetsSubDirectory: 'static',

    assetsPublicPath: '/',

    proxyTable: {},

    // CSS Sourcemaps off by default because relative paths are "buggy"

    // with this option, according to the CSS-Loader README

    // (https://github.com/webpack/css-loader#sourcemaps)

    // In our experience, they generally work as expected,

    // just be aware of this issue when enabling this option.

    cssSourceMap: false

  }

然后运行就变成8088端口了。
