Running stack install yesod-bin --install-ghc fails at ghc decompressing with message: "Problem while decompressing C:\Users\user\AppData\Local\Programs\stack\x86_64-windows\ghc-8.4.4.tar.xz"
I try to run this command on Windows 10 64 bit, cmd, with the latest Haskell platform version 8.6.5-core-x86_64 after creating a project with yesod-sqlite template. I've tried a different version as well, with same result. stack install yesod-bin-1.4.11 --install-ghc
> stack install yesod-bin --install-ghc

stack build retries and fails at the same point. I'd expect some proper install instead.
Update: stack setup --verbose output:

Another cabal install attempt revealed that the network package is not willing to compile in Windows at all, at least not in the generic command prompt (cmd), but it requires MingW, MSys or Cygwin. I tried the latter for cabal self update, and it succeeded. Then still in Cygwin, I tried the stack install again, and it worked.
Unfortunately the stack command's output didn't provide any hint towards Cygwin, and left me clueless for a while. In Cygwin however, Yesod builds and starts, and demo website works properly. Maybe some emphasis against generic windows command prompt could help to avoid such misunderstandings.
