go modules - Replace Directive Not Functioning: Resolving Replacement Module Path Error

When attempting to utilize a local package with go modules, a common error can surface: "replacement module without version must be directory path (rooted or starting with .)." This error indicates an incorrect path structure in the replace directive within the go.mod file.

Understanding the Replace Directive

The replace directive in go.mod allows users to substitute a dependency with a different version or source. However, the path specified for the replacement module must conform to specific criteria:

  • Absolute Path: An absolute path must start with a root directory character (/) and specify the full directory location of the replacement module.
  • Relative Path: A relative path must be relative to the module's root directory.

Resolving the Path Structure Error

The provided example in the question has the following structure:

goweb/
  └─ src/
    └─ mypack/
      └─ go.mod (local package)
  go.mod (module containing the replace directive)

To resolve the path structure error, ensure that the path specified for the replacement module is either an absolute or a relative path that follows the criteria above.

Correcting the Replace Directive

  1. Use Absolute Path: If mypack is not a sibling of the module's root, specify its absolute path as follows:

    replace mypack => /absolute/path/to/mypack
  2. Use Relative Path: If mypack is a sibling of the module's root, specify its relative path as follows:

    replace mypack => ../mypack

Additional Notes

  • The replacement module, mypack, must contain a go.mod file to be recognized as a valid module.
  • Avoid using vendor directories as they are deprecated.

By following these steps, you can resolve the "replacement module without version must be directory path" error and successfully use your local package with go modules.
