现象：项目中使用了websocket（不管何种websocket库，原生websocket、io.socket）,只要websocket服务停止，npm run serve 就崩溃，如果一致调试前后端程序的话，崩溃了得重启，此问题一致困扰了我好几年了，一直没解决，今天终于借助ChatGpt解决了。

Proxy error: Could not proxy request /?secret=7315d6f0-ed6e-11ed-abb2-0ddfab4339a2&EIO=3&transport=websocket from localhost:8086 to http://127.0.0.1/socket.io/

解决办法：

process.on('uncaughtException', (err) => console.error(err))

原因：
