Using plain GHC version /bin/sh: ghc: command not found

[cideM]

I just installed the HIE as per the instructions on MacOS High Sierra.

git clone https://github.com/haskell/haskell-ide-engine --recursive
make build-all

Also made sure to add

"languageServerHaskell.useCustomHieWrapper": true,
"languageServerHaskell.useCustomHieWrapperPath": "hie-wrapper",

to the VSC settings. I then created a new project with stack new foo. Upon opening the project in VSC (latest insider build), the Haskell LSP crashes repeatedly. Here's the output from, well, output.

I assume it's trying to determine the version by simply calling ghc rather than stack ghc --...or something?

Okay a simple stack upgrade fixed it. https://github.com/commercialhaskell/lts-haskell/issues/164

Could you please have a look into. Was this the same patch you got. Not able to run 'make'.

@shrin18 you're able to run make, you just don't have a ghc in your PATH. Stack doesn't put GHC in PATH and it's in no way related to HIE. Try asking in some haskell chat like #haskell on freenode, stack overflow or haskell subreddit.

Thanks. Fixed it !

@shrin18 What was the solution?
