go cmd unavailable for go-pre-compile or go-post-compile

[zkrzyzanowski]

Hi,
I've added a bin/go-post-compile file as written in the docs here

When I try and run a deploy, i get the following error

/tmp/codon/tmp/buildpacks/c92a29ce0eaa662656e0e35917663a37ea9acb68/bin/compile: line 84: /tmp/build_0859c912/bin/#!/bin/bash
set -e
go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/[email protected]: No such file or directory

No matter what go commands I run, I still get the same error, i.e running go version, attempting to install another go pkg

Based on this comment in a separate issue, it appears that the build pack doesn't set any run time environment variables and that the go toolchain is not available to the run time environment

How would you recommend we install go packages needed at release time?

I tried setting GO_INSTALL_TOOLS_IN_IMAGE and GO_SETUP_GOPATH_IN_IMAGE to true according to this article, but that didn't work either unfortunately.
