[Haskell-cafe] How to update a cabal dependency automatically

[ye yan]

git add -p works very good in this case, thank you for your advise. Just 
wondering how does cabal solve dependencies?

I updated my cabal file. ghci works find with my development box. but when 
I checkout with other computer I got a dependency error. It seems cabal 
failed to detect the correct library version I am using in ghci. Or just 
because for parsec library I have multiple versions installed?
