Try a different Go version

Oct 13, 2025 by wbrum.org 56 views

Introduction

Pulumi is a popular infrastructure-as-code (IaC) platform that allows developers to define and manage cloud infrastructure using a variety of programming languages, including Go. However, when using the pulumi package add command to add a Terraform module to a Go project, some users have encountered an error message indicating that the Go language info failed to import. In this article, we will explore this issue in detail and provide a solution to resolve it.

What happened?

To reproduce this issue, let's create a new Go project using the pulumi new go command:

$ pulumi new go
$ pulumi package add terraform-module terraform-aws-modules/s3-bucket/aws 4.5.0 bucket

warning: using pulumi-resource-terraform-module from $PATH at /Users/guin/go/src/github.com/pulumi/pulumi-terraform-module-provider/bin/pulumi-resource-terraform-module
Successfully generated a Go SDK for the bucket package at /Users/guin/go/src/github.com/pulumi/module-experiments/golang-bucketmod/sdks/bucket
error: failed to import go language info

As we can see, the pulumi package add command fails with an error message indicating that the Go language info failed to import. This error message is not very informative, and it's unclear what Go package to import in the main program.

Example

The example above demonstrates the issue. We create a new Go project using pulumi new go and then attempt to add a Terraform module using pulumi package add. However, the command fails with an error message indicating that the Go language info failed to import.

Output of `pulumi about`

To gather more information about the issue, let's run the pulumi about command:

CLI          
Version      3.153.0
Go Version   go1.24.0
Go Compiler  gc
