我已经尝试解决这个错误 5 个小时，但它不起作用。:c 请帮助我。

这是丑陋的控制台错误消息（我不擅长格式化 sry :c）：

P:\.Projektek\lireddit-server>yarn dev
yarn run v1.22.10
$ nodemon dist/index.js
[nodemon] 2.0.7
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json  
[nodemon] starting `node dist/index.js`     
[discovery] ORM entity discovery started, using ReflectMetadataProvider

[nodemon] clean exit - waiting for changes before restart

这太痛苦了。
