As explained in https://discuss.dgraph.io/t/go-modules-on-badger-and-dgraph/4662, Go Modules force an import path rename that currently breaks support for most other dependency management systems, including dep. It seems an effort is being made to add support for this import path renaming by patching the go tool itself, but until the community hasn't settled and Go Modules is an easier option to adopt, we are simply not supporting them. For those willing to use badger v2 from Go modules it is still very simple, you might notice that once you set the version to be v2.0.0 a +incompatible will be added to it indicating the dependency has not opted-in into Go Modules. That's normal and not to be a concern.
