Description:

When trying to install a Haskell package with cabal install, or buid with cabal build, I end up with a bunch of messages of missing packages:

src/Control/Monad/Base.hs:17:8: error:
Could not find module ‘Prelude’
There are files missing in the ‘base-4.10.0.0’ package,
try running 'ghc-pkg check'.
Use -v to see a list of the files searched for.

17 | module Control.Monad.Base
| ^^^^^^^^^^^^^^^^^^

src/Control/Monad/Base.hs:22:1: error:

Moreover if I run ghc-pkg check I get things like:
