我正在使用 VS 代碼編輯器在 go 中編寫 CLI。我無法弄清楚如何調試代碼部分。我的目錄結構是：- test  - main.go  - cmd    - login.go    - root.go我已在 login.go 中設置斷點，但如果我在此文件中運行“開始調試”，則會出現錯誤Can not debug non-main packageProcess exiting with code: 1我嘗試在 main.go 中運行調試器，但調試器不會轉到 login.go 文件，因為我們沒有明確編寫test loginAPI server listening at: 127.0.0.1:48423A longer description that spans multiple lines and likely containsexamples and usage of using your application.
