How to resolve the issue of golang subdirectory package…

In Go, packages in subdirectories cannot be directly referenced and need to be correctly referenced using relative or absolute paths. Here are some possible solutions:

1. Relative paths can be used to reference packages located in subdirectories. For example, if your package is in ./subdir/pkg, you can reference it in your code using import “./subdir/pkg”.
2. Using absolute paths: You can reference packages in subdirectories using absolute paths. For example, if your package is in github.com/username/project/subdir/pkg, you can reference the package in your code by using import “github.com/username/project/subdir/pkg”.
3. GOPATH configuration: Ensure that your project path is included in the GOPATH environment variable. If your project path is not within the GOPATH, Go will be unable to correctly resolve packages in subdirectories.
4. Module usage: If your project utilizes Go modules to manage dependencies, make sure to correctly initialize and utilize the modules. Run ‘go mod init’ in the project’s root directory to initialize the modules, and use ‘go mod tidy’ to ensure correct module dependencies.
5. Check the package name: Make sure the packages in the subdirectories have the correct package name and exported functions/methods. The package name should correspond to the directory name, and the exported functions/methods should start with uppercase letters.

If the above solutions do not work, providing more detailed information may be necessary to better understand and address the issue.
