问题
I'm having the most difficult time trying to understand what I am doing wrong with installing haskell on windows. I've downloaded the platform binary and ran the .exe file. Afterwards the instructions on their hackage website tells me to run cabal install gloss.
Whenever I try this in their GHCI shell, I get the following errors:
<interactive>:1:1: Not in scope 'cabal'
<interactive>:1:7: Not in scope 'install'
<interactive>:1:15: Not in scope 'gloss'
I know for a fact cabal install gloss isn't the correct command, but I can't seem to find anything online that'll help me figure this out. Would much appreciate your help.
Thanks!

Click Start → Run. Type cmd and press Enter. A Windows command prompt window will appear, in which you can run the cabal install gloss command.
