cabal: cannot configure repa-2.2.0.1. It requires base ==4.4.*
For the dependency on base ==4.4.* there are these packages: base-4.4.0.0 and
base-4.4.1.0. However none of them are available.
base-4.4.0.0 was excluded because base-4.3.1.0 was selected instead
base-4.4.0.0 was excluded because of the top level dependency base -any
base-4.4.1.0 was excluded because base-4.3.1.0 was selected instead
base-4.4.1.0 was excluded because of the top level dependency base -any
