How Can I Access Local Packages Within My Go 1.11 Modules?

Accessing Local Packages within Go 1.11 Modules

Problem Statement

When attempting to access a local package in a Go module with a project structure similar to the one described below, the compilation fails with a "cannot find module" error.

Solution

To access local packages within a Go module, you need to modify the project's go.mod file and use the replace directive. This directive allows you to specify a local path for a package that is not available in a remote repository.

Steps to Resolve the Issue

1. Define the Modules:

   • In the example provided, the module for the main project can be defined as github.com/userName/mainModule.
   • The module for the platform package can be defined as github.com/userName/otherModule.

2. Modify go.mod File:

   • Add the following lines to the go.mod file:

   • Replace local physical path to the otherModule with the absolute path to the root directory of the otherModule directory.

3. Import the Package:

   • In main.go, import the desired package from otherModule:

Additional Information

• The replace directive allows you to replace the remote dependency with a local path, even if they have the same version number.
• Modules are collections of packages. In Go 11, you can use modules to manage dependencies and versions.
• For a comprehensive introduction to Go modules, refer to the official documentation.
