TypeError: Cannot read property 'split' of undefined

This could happen only if you don't have PATH set. Which usually means something's gone horribly wrong. Either that, or Atom botched an update. Try reinstalling the package, or cleaning compilation cache (.atom/compile-cache).

[cnd]

it's happened after fresh installation on 1.7 beta 0 / cleaning cache doesn't help

[lierdakil]

This seems related to https://github.com/atom/atom/pull/11054 then

Check to see if process.env is sane. Especially if there's PATH there. If you're on Windows, check for different capitalizations as well.

You can use dev. console to check for those.

Thanks.

I have edited the coffeescript file and changed process.env.PATH to process.env.Path and now it seems to work

[lierdakil]

@DominikDitoIvosevic -- that's not a solution though. Windows has this weird thing where it collects differently capitalized environment variables into one, and node did collect all of those (path, Path, etc) into PATH. I wonder if atom/atom#11054 breaks this.

[cnd]

@DominikDitoIvosevic yes, thanks it looks like step forward

now I get my regular

message: Invalid option `-p'

Usage: ghc-mod browse [-o|--operators] [-d|--detailed] [-q|--qualified] MODULE

[cnd]

And if I even comment out -p from coffee I'm getting:

CabalHelper\Licenses.hs:38:28:
    Not in scope: `lookupComponentId'
    Perhaps you meant one of these:
      `lookupComponent' (imported from Distribution.Simple.LocalBuildInfo),
      `localComponentId' (imported from Distribution.Simple.LocalBuildInfo)

[cnd]

ah this should be related https://github.com/DanielG/cabal-helper/commit/c2d116272b448342629e6beb73fe7a464e2245d3

[cnd]

however maybe it's not fully sychronized with live cabal sources

@Heather, for the love of all that is holy, disable 'Experimental' option in haskell-ghc-mod. It's not what you think it is.

Let me know if there are still PATH-related issues on Windows after 1.11.4.

[cnd]

issue with PATH is gone
