我正在使用 VS 代码编辑器在 go 中编写 CLI。我无法弄清楚如何调试代码部分。我的目录结构是：- test  - main.go  - cmd    - login.go    - root.go我已在 login.go 中设置断点，但如果我在此文件中运行“开始调试”，则会出现错误Can not debug non-main packageProcess exiting with code: 1我尝试在 main.go 中运行调试器，但调试器不会转到 login.go 文件，因为我们没有明确编写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.
