What Is the v2+ Import Path Problem in Go Modules

Fix the v2+ import path error by adding the major version suffix (e.g., /v2) to the module path in go.mod and all import statements.

The v2+ import path problem occurs when a Go module with a major version v2 or higher is imported without the required /v2 suffix in the import path. Go modules enforce that any module with a version v2 or greater must have its major version included in the import path to distinguish it from the v1 version. To fix this, ensure your go.mod file declares the correct version and update all import statements to include the suffix.

// go.mod
module example.com/myproject/v2

go 1.21

// main.go
import (
	"example.com/myproject/v2/pkg"
)
