Should go.mod not be added to the project?

[tithamane]

I'm learning how to use go modules and trying to convert my project to use them but I'm getting an error from this package when try to build it.

When I run: go get github.com/golang/freetype then I get

go: finding github.com/golang/freetype latest
go: finding github.com/golang/freetype/truetype latest
go build github.com/golang/freetype/truetype: no Go files in

When I try to build my code I get

go: finding github.com/golang/freetype/truetype latest
go: finding github.com/golang/freetype latest
../../../go/pkg/mod/github.com/llgcode/draw2d@v0.0.0-20180825133448-f52c8a71aff0/draw2dimg/ftgc.go:16:2: unknown import path "github.com/golang/freetype/truetype": cannot find module providing packagegithub.com/golang/freetype/truetype

It could just be the fact that I'm not using these modules properly or maybe I need to restructure my code, I just though I should ask about this just in case it could help solve my problem.

If I can get it working again, I'll close this issue.

I can get this working with go modules.

You shouldn't need go.mod/go.sum for this to work.
Can you share how you created your repo (the commands you ran), and where it is in relation to your GOPATH? I think you might have issues with it being in your GOPATH, based on the ../../../go/pkg, I'd recommend moving it out of your GOPATH or trying export GO111MODULE=on then building again.
