I'm trying to install GHC on windows with the following script (and put ghc in path), but it fails when I try to run ghci --version. I think there is something wrong with the script.
install:
- ps: Invoke-WebRequest "https://downloads.haskell.org/~ghc/8.0.2/ghc-8.0.2-i386-unknown-mingw32-win10.tar.xz" -OutFile "ghc-8.0.2-i386-unknown-mingw32-win10.tar.xz"
- 7z x ghc-8.0.2-i386-unknown-mingw32-win10.tar.xz
- ps: $env:path += "C:\projects\haskell-interactive-mode\ghc-8.0.2-i386-unknown-mingw32-win10.tar\ghc-8.0.2\bin"
- ps: ghci --version
I tried your command on local Windows machine and I see that 7z x ghc-8.0.2-i386-unknown-mingw32-win10.tar.xz results in ghc-8.0.2-i386-unknown-mingw32-win10.tar file, not folder. If you unzip it further with 7z x ghc-8.0.2-i386-unknown-mingw32-win10.tar, it unzips into real folder named ghc-8.0.2 with bin subfolder and ghci.exe file.
However I think that simpler it would be use Chocolatey package. This works for me well:
- choco install ghc
- refreshenv
- ghci --version
