hey guys, I have a problem with how cabal is installing packages on ubuntu. I installed haskell via ghcup. when i run cabal, it doesn't update my package.conf.d and i don't even know where it is installing these packages (I suspect it is in /home/.cabal) and i don't know how to make this work. has anyone faced this problem before? how did you solve it?

Hi! Are you running cabal install? And what are you trying to achieve exactly?

cabal install is meant to build executables and copy them somewhere like ~/.cabal/bin, which you put in PATH or something like that. If you just need to depend on some package as a developer, you don't need cabal install

I see, so should i manually download the tar.gz for quipper from hackage and unzip it in the right directory?

You should probably put the quipper dependency in a .cabal file in your project's directory. If you don't have a .cabal file, you should run cabal init

Probably it would be more convenient for you...
