So, I am at the point, where I want to expand my skills and start working with libraries. And here is where I run into an unbreakable brick wall. I have started numerous Stack projects to follow along tutorials or build my own projects. Every time I get these Errors after following the exact steps on the Stack site, or what the tutorials say I should do.
1: Could not find module ‘Data.Gi.Base’ or ‘aeson’
It is not a module in the current program, or in any known package.not found
2: I edit the package.yaml file like that :
dependencies:
- base >= 4.7 && < 5
- gi-gtk == 3.0.*
- gi-gtk-hs
- haskell-gi-base
and get that output after stack build :
haskell-gi-base> version >=2.42 is required but it could not be found.
haskell-gi-base>
Progress 1/15
…
Process exited with code: ExitFailure 1
I really need some help.
