Windows Installation Fails with 'cabal: createProcess does not exist.'

[andersyr]

On windows I followed the README.md installation instructions: Downloaded current versions of Git, Stack, and Shake. Applied the optional Win32 Long Paths. Cloned HIE, executed stack ./install.hs hie-8.6.3 and received the below error. Any help is appreciated as I'm quite unfamiliar with HIE and Shake.

Warning: The update command is a part of the legacy v1 style of cabal usage.

Please switch to using either the new project style and the new-update command
or the legacy v1-update alias as new-style projects will become the default in
the next version of cabal-install. Please file a bug if you cannot replicate a
working v1- use case with the new-style commands.

You probably have to add C:\Users\Kaz\AppData\Roaming\local\bin to your PATH.
Stack installs executabels into this directory and it needs to find these executables again. I think, there is a notice about it in the README.
EDIT: hie executables will also be installed into that directory, thus, you need it in your PATH anyways.

Thanks for the quick reply. I was curious about that earlier as well. Windows shows it in my PATH environment under System Properties > Environment variables.

Edit: Oops, I misinterpreted on my last edit. Looking through some pages on the 'does not exist' cabal error, shows it could possibly be a networking issue or a corrupted package list.

I'm running stack ./install.hs hie-8.6.3 again to test if it was a temporary networking issue and will revert to a previous package list if the build continues to fail.

Be aware of #1008. You won't be able to build it anyway.

Ah, my apologies for missing that. I just finished setting up 8.6.2 and everything is working splendidly. Thanks a bunch for the assistance! =) Cheers
