localhost:8081打不开?后台和数据库都正常运行,一个月以前的备份可以打开,后面的打不开.查8081端口是node占用的.什么原因?

There are many reasons, force kill.

Resolved. Reason: After changing the data type of schemas, it conflicts with the data type saved in js, causing the local server to fail to start.

Kill applications that are using port 8081.
Or change to another port.
