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。
