Hi all,
a very basic question, that I cannot solve alone:
How do I load modules from hackage into ghci ?
Say, I have a module arrows.hs :
{-# LANGUAGE Arrows #-}
module Main where
import Control.Arrow
import Control.Monad
import qualified Control.Category as Cat
import Data.List
import Data.Maybe
import System.Random
I get the error in ghci:
% ghci arrows.hs
GHCi, version 8.10.6: https://www.haskell.org/ghc/ :? for help
[1 of 1] Compiling Main ( arrows.hs, interpreted )
arrows.hs:9:1: error:
Could not find module ‘System.Random’
Use -v (or `:set -v` in ghci) to see a list of the files searched
for. |
9 | import System.Random
| ^^^^^^^^^^^^^^^^^^^^
Failed, no modules loaded.
Prelude>
System.Random is in the package "random" from hackage, where the other
modules are in the package base.
I cannot find a solution in the doku that works :-(
Thanks for help!
