cabal sandbox + haskeline
cabal, haskell
Solution
Either use `cabal repl` like Joseph mentioned or you can explicitly pass the package db to the GHCi shell relative to your current working directory.
ghci -no-user-package-db -package-db .cabal-sandbox/*-packages.conf.d YourModule.hs
It's recommended that you just use cabal.
Problem
``` cabal sandbox init cabal install haskeline ... installs successfully ... ghci Prelude> :module +System.Console.Haskeline <no location info>: Could not find module `System.Console.Haskeline' ghc-pkg list haskeline .. not found .. ``` What do I have to do get haskeline to work with cabal sandbox? If I install haskeline normally (no sandbox) it is fine (ghc-pkg list haskeline -- found it).
