go mod vendor: parsing go.mod: unexpected module path "gopkg.in/h2non/gock.v1"

[James Mills]

I run into an error trying to run go mod vendor (we sadly are using Go11Modules + Vendoring at the moment):

$ go mod vendor
go: github.com/h2non/gock@v1.0.14: parsing go.mod: unexpected module path "gopkg.in/h2non/gock.v1"
go: error loading module requirements

Any ideas why go mod is complaining here?

[James Mills]

It seems to me that your module def in go.mod is what go mod doesn't like:

$ GOPROXY="" go get -u github.com/h2non/gock
go: github.com/h2non/gock@v1.0.14: parsing go.mod: unexpected module path "gopkg.in/h2non/gock.v1"
go get: error loading module requirements

The work-around here is to use a replace in my go.mod:

$ git diff go.mod
diff --git a/go.mod b/go.mod
index 5b494df..67fad48 100644
--- a/go.mod

I found a similar work-around by searching around. Example: go-resty/resty#230

From doing some grep'ing around your codebase; it looks like you mix github.com/ and gopokg.in/ import paths for your own package -- I believe this is confusing go mod utterly. Can you fix this? :)

Seconding the request to have this fixed. :)

Thanks for the workaround, @prologic.

This is because github.com/h2non/gock is supposed to be imported as gopkg.in/h2non/gock.v1, according to its go.mod file. When go mod downloads the module, it checks whether the module declaration matches the import path. The replace statement is just a workaround. You should change the imports and go get command
