最近在学vue
准备利用官方的脚手架先搭建环境然后写一个小demo，结果各种不顺利

$ npm install vue-cli -g # 顺利完成
$ vue init webpack vue-demo #顺利
$ cd vue-demo/
$ npm install # 遇到问题了
$ npm run dev # 遇到问题了

解决办法

node版本低，下载高版本

  • 卸载以前node版本，下载新版本重新安装

  • 使用 npm install -g n 可以更新node 但是很悲剧，我的报错

npm run dev # 遇到问题- 解决办法

vue-project@1.0.0 dev E:MySoftwaretestGitwebpackvue-projectnode build/dev-server.js "8088"
events.js:160

  throw er; // Unhandled 'error' event

$ npm dev run --port 1314 # 不行啊，，报错 疯了

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
  }
$ npm run dev --port 8088 # ok 访问http://localhost:8088/查看结果
