메인 실행 같은 명령어 이걸 해야 내가 쓴 코드가 컴파일 되는것 같다.

그리고

Note: No local targets specified, so a plain ghci will be started with no
      package hiding or package options.

      You are using snapshot: lts-19.16

      If you want to use package hiding and options, then you can try one
      of the following:

      * If you want to start a different project configuration
        than /Users/globalyoung/.stack/global-project/stack.yaml, then you can use
        stack init to create a new stack.yaml for the packages in the
        current directory.

      * If you want to use the project configuration
        at /Users/globalyoung/.stack/global-project/stack.yaml, then you can add to its 'packages' field.

In a new powershell or cmd.exe session, now you can...

Start a simple repl via:
  ghci

Start a new haskell project in the current directory via:
  cabal init --interactive

Install other GHC versions and tools via:
  ghcup list
  ghcup install <tool> <version>

open the "Mingw haskell shell"
and the "Mingw package management docs"
