npm run dev報錯，events.js:160 throw er; // Unhandled 'error' event

錯誤代碼以下：

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

  throw er; // Unhandled 'error' event
  ^

解決方案：

網上找不少帖子，都沒有寫解決辦法，本身來嘍，也是神奇的錯誤

最後，神奇的是，錯誤竟然被哦改好了

解決辦法

進入 vue-demo/config/index.js

dev: {
    env: require('./dev.env'),
    port: 8088,        # 注意了啊。。。修改爲你要的端口，接着運行代碼就看到效果了
    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
  }

而後運行就變成8088端口了。
