Why Does 'go install' Fail with 'local import' Errors for Non-Local Go Packages?

Local Import in Non-local Package in Go

When working with a specific file structure, it is important to understand the implications of using local imports within non-local packages.

Consider the following scenario:

• File structure:

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

• GOPATH: /Users/clarkj84/Desktop/LearningGo

When executing the command /usr/local/go/bin/go install jacob.uk.com from the src folder, an error may be encountered: local import "./greeting" in non-local package.

Explanation:
This error occurs because local imports (e.g., ./greeting) are not allowed when specifying a non-local package to install (jacob.uk.com).

Solution:
To resolve this issue, you can either:

1. Change the working directory to src/jacob.uk.com and execute go install without specifying the package.
2. Use an absolute import path: import "jacob.uk.com/greeting"

Best Practice:
It is recommended to avoid using local imports in general. Instead, use absolute import paths to ensure portability and avoid potential errors.
