go.mod has post-v2 module path at revision v2.0.0

Question

I have a rest api I built in Go with gin that has been working for months now on my local machine running 1.12.1. I decided it was going to a docker deploy so I started building with 1.12.6 when I started see errors during module retrieval. I went back to my local machine, ran running 1.12.1 and ran go clean -modcache, now the error is there as well. I've tried regenerating multiple times even editing the go.sum file to different versions of gofight but I'm lost and run out of ideas.

The output w/error:

go: github.com/appleboy/[email protected]+incompatible: go.mod has post-v2 module path "github.com/appleboy/gofight/v2" at revision v2.0.0
go: error loading module requirements

go.sum (the line for the module in question, posting the whole thing exceeds SO post length)

github.com/appleboy/gofight v2.0.0+incompatible/go.mod h1:H/tvof1oZHnZdlBd+AeODZGkk1C+D2na0NXr0iXuZHA=

I've also tried adjusting the go 1.12 statement in go.mod for the specific subversions I'm attempting to build with but that had no effect.

What does this error mean? How can I fix it?

Answer 1

A number of packages were outdated, the main fix was to run the new install command for gin-jwt, go get github.com/appleboy/gin-jwt/v2

Ultimately though I just nuked my go.mod and go.sum and did a fresh sync in Goland IDE. Everything is working on 1.12+
