I'm trying Conrad Barski's haskell tutorial[1] but it looks like runhaskell cannot find a few packages that will be necessary in the tutorial. [1]:http://lisperati.com/haskell/ I installed ghc, ghc-random and ghc-regex-compat. I typed up the program as instructed. Then I ran "runhaskell tutorial.hs" and got this output: 2 packages in profile jesse@piranhaplant ~/Documents/haskell$ runhaskell tutorial.hs
tutorial.hs:2:1: error: Could not find module ‘Text.Regex’ Perhaps you meant Text.Read (from base-4.12.0.0) Use -v to see a list of the files searched for. | 2 | import Text.Regex | ^^^^^^^^^^^^^^^^^ tutorial.hs:3:1: error: Could not find module ‘System.Random’ Use -v to see a list of the files searched for. | 3 | import System.Random | ^^^^^^^^^^^^^^^^^^^^ I searched hackage and hoogle to find which packages I would need to install, and confirmed I have the correct packages installed, but ghc can't seem to find them. I even changed the version of ghc and logged into a terminal to see if I needed a different version. No difference. Can somebody help me out please?
