How to Correctly Import Local Packages in Go?

Importing Local Packages in Go

When working with localized code in Go, importing local packages can sometimes encounter challenges. Here's a detailed analysis of a common issue and its resolution:

Issue:

In an attempt to localize the import statement for packages located in "/home/me/go/src/myapp," the following changes were made:

import (
    "./common"
    "./routers"
)

However, upon running "go install myapp," the following errors occurred:

can't load package: /home/me/go/src/myapp/main.go:7:3: local import "./common" in non-local package

Additionally, using "common" and "routers" without the "./" prefix resulted in:

myapp/main.go:7:3: cannot find package "common" in any of:
    /usr/local/go/src/common (from $GOROOT)
    /home/me/go/src/common (from $GOPATH)
myapp/main.go:8:2: cannot find package "routers" in any of:
    /usr/local/go/src/routers (from $GOROOT)
    /home/me/go/src/routers (from $GOPATH)

Solution:

The issue stems from Go's import path convention. Go's starting directory for imports is "$HOME/go/src". To resolve this, simply add the "myapp" prefix to the package names in the import statement:

import (
    "log"
    "net/http"
    "myapp/common"
    "myapp/routers"
)

This modification ensures that the import paths are correct and will resolve the errors encountered during compilation.
