Running on windows 10, GHC interactive fails to load any standard packages. The startup  message does not include the prompt about initializing packages do, as shown commonly on Haskell getting started tutorials. Instead I see:

GHCi, version 7.10.3: http://www.haskell.org/ghc/  :? for help

Prelude> :l Data.Text

<no location info>: module ‘Data.Text’ is a package module

Failed, modules loaded: none.

Prelude>

Any pointers on what to do next?
