How to Run Code from a Forked GitHub Repository with Go Packages?

Go: Navigating Repository Forks with Go Packages

While working with Go packages, you may encounter errors like "use of internal package not allowed" when running code from a forked GitHub repository. This arises when attempting to run test code from a forked repository, such as zoonoo/go-ethereum in your instance.

Go's package system prioritizes strict dependency management by requiring the proper import paths for each package it utilizes. This includes your own and any third-party packages. When forking a repository, you essentially create a copy with its own distinct namespace. Therefore, you cannot directly reference internal packages that are specific to the original repository.

To resolve this issue and successfully run code from a forked repository, it's crucial to modify the import paths of affected dependencies. The dependency paths must reflect the structure of your forked repository. For instance, instead of accessing internal packages from "github.com/ethereum/go-ethereum/internal/ethapi," you would need to import them from the appropriate path within your forked repository's directory structure, such as "github.com//go-ethereum/internal/ethapi."

Go's package system supports repository forks, provided that you adhere to its import path conventions. By adjusting the import paths, you can ensure that your code correctly references dependencies and executes smoothly from your forked repository.
