Why Am I Getting the 'package XXX is not in GOROOT' Error When Building My Go Project?

"package XXX is not in GOROOT" When Building a Go Project

Context

The issue arises when attempting to build a Go project, and the following error appears: "package project/game is not in GOROOT (C:Gosrcprojectgame)".

Root Cause

This error typically occurs when:

• GOROOT, GOPATH, and GOBIN environment variables are not properly set.
• The Go project is not structured correctly.
• The go.mod file is missing or not in the project root.

Resolution

1. Configure Environment Variables

If you upgraded to a newer Go version (1.13 ), environment variables like GOROOT, GOBIN, and GOPATH are no longer recommended.

2. Correct Project Structure

Ensure that your project has a go.mod file at the project root and the following directory structure:

|- project
    |- game
        |- entity
        |- game_stuff.go
    |- server

3. Use go mod

Instead of rely on environment variables, use Go Modules (go mod) to manage module dependencies.

cd project
go mod init remote-repo.com/username/repository

4. Run Commands from the Module Root

Commands should be executed from the project root directory. For example:

go run server

5. Specify Full Module Paths

When using go commands, especially from outside the module root, specify the full package path, which includes the vendor URI. For example:

go test github.com/username/repository/project/game/entity

6. Set GOPATH If Necessary (Optional)

For older Go versions, you can optionally set GOPATH to the workspace path where your project is located. Ensure that GOPATH points to the correct path.

GOPATH=C:\Users\username\go

Example

To build the server package in the provided directory structure:

cd project/server
go build project/server

This command should successfully build the server package without the "package XXX is not in GOROOT" error.
