Not pulling down correct version of happy #563

Haven't looked into why this still is an issue in a while but I think this is the one: haskell/cabal#220 which also links to this: haskell-suite/haskell-src-exts#14 |

Hi,
I'm new to Haskell and I was setting up my environment. I tried to install ghc-mod via cabal but it fell down due to the correct version of happy not being in my distribution (ghc-mod is expecting a version >= 1.17). It was easily fixed by doing cabal install happy which then proceeded to pull down version 1.19. I'm just wondering whether that is an issue with the ghc-mod build script in that if it doesn't find the correct version of happy, it doesn't try to pull down the right version? Sorry if I am missing something here, I am totally new to Haskell and cabal. Below is a copy of the install activity:
