I can't get haskell's stack to work on my Mac.
I installed haskell by:
brew cask install haskell-platform
Which is specified here: https://www.haskell.org/platform/mac.html#osx-homebrewcask
I've also tried installing via the downloadable package at the same site.
I do the following commands:
stack new my-project
cd my-project
stack setup
stack build
stack exec my-project-exe
Per the documentation here: https://docs.haskellstack.org/en/stable/README/#quick-start-guide
And I immediately see this:
[1] 43017 killed stack exec my-project-exe
I've also tried many other ways of installing haskell. I've actually been able to get something compiled and executed just using cabal, but I can't then get hlint, hindent, or ghc-mod to work, they all return a similar message to the one above. I'd love to be able to work with HaskForce in IntelliJ on my Mac, but I've never had luck getting haskell to work.
System Specs
- macOS 10.12.6 (16G29) (Sierra)
- Fresh uninstall/reinstall of XCode (accepted terms)
- brew as package manager
Here's a gif of what happens as well: https://i.stack.imgur.com/P95g1.jpg
UPDATE
I blew away all stuff related to ghc, stack, and cabal and then installed this way https://haskell-lang.org/get-started
Writing the little HelloWorld.hs script worked fine and showed Hello, World
However, doing
stack new someproj
cd someproj
stack build
Resulted in this:

Which I've seen before and was actually one of my initial problems
UPDATE 2: Created GitHub Issue
Here's the issue: https://github.com/commercialhaskell/stack/issues/3487
After talking with folks on #haskell IRC they recommended I create an issue as this is very peculiar behaviour from what I understand. I'll try make sure whatever we find out here is pushed up there too.
