Why Does Go Return a 'local import in non-local package' Error, and How Can It Be Resolved?

Local Import in Go Package

In Go, the import statement is used to import packages. Packages are used to organize code into logical units. When importing a package, you can use a local import or a non-local import.

A local import imports a package from the current working directory. A non-local import imports a package from another directory.

The Error

The following is a file structure:

.
├── bin
│   └── hello
├── pkg
└── src
    └── jacob.uk.com
        ├── greeting
        │   └── greeting.go
        └── helloworld.go

with the following GOPATH:

/Users/clarkj84/Desktop/LearningGo

If you execute the following command within the src folder:

/usr/local/go/bin/go install jacob.uk.com

you will get the following error:

local import "./greeting" in non-local package

This error occurs because you are using a local import in a non-local package.

The Solution

To fix this error, you can change the working directory to src/jacob.uk.com and then execute go install without specifying the package. If you have a helloworld.go file with the following content:

package main

import "./greeting"

func main() {

}

you will get a compile error stating "imported and not used." Once you use something from the imported greeting package, it should compile.

However, it is not recommended to use local imports. Instead, you should use the following import statement:

import "jacob.uk.com/greeting"

By using this import statement, you will be able to compile, run, and install your code from anywhere.
