Re: [Haskell-beginners] Ambiguous module name `Prelude': it was found in multiple packages (trying to install HXQ)

Ambiguous module name `Prelude': it was found in multiple packages: base haskell98-2.0.0.2

just guessing: https://hackage.haskell.org/package/HXQ -> https://hackage.haskell.org/package/haskell98 -> base (==4.7.*), what base version was installed on your pc before you tried to install HXQ? is it possible to install multiple base versions?
