Install GHC (Glasgow Haskell Compiler) # On Ubuntu/Debian sudo apt install ghc On macOS (using Homebrew) brew install ghc On Windows (using Chocolatey) choco install ghc 2. Install Cabal (the build tool) # Using your distro's package manager (often outdated) sudo apt install cabal-install Recommended: Use ghcup (Haskell toolchain manager) curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh ghcup install cabal latest
