Question

我正在使用vue-cli webpack模板来生成我的项目，并且我想将请求代理到单独的后端服务器。但是我收到了如下错误消息。

有谁可以告诉我我的编码是什么问题？

非常感谢！

Vue.use(VueRouter);

const router = new VueRouter(routerConfig)

export default{

请执行以下操作：

npm install --save-dev concurrently

在package.json上添加到scripts：

"server": "node server.js",
"go": "concurrently --kill-others \"npm run dev\" \"npm run server\""

从现在开始使用：

npm run go

当然，您可以将go重命名为您想要的任何内容。
