Haskell-ghc-mod: ghc-mod failed to launch. It is probably missing or misconfigured. ENOENT

Shahala1 commented 8 years ago

Hello,

I have the same issue as #104. Tried using the suggested solutions to no avail. What I've tried:

Installing ghc-mod via Cabal as suggested by Dattaya
Changing both "ghc-mod path" and "additional paths" in the ghc-mod package settings. Added the following: C:\Users\MyUser\AppData\Roaming\cabal\bin, C:\Users\MyUser\AppData\Roaming\cabal\packages\hackage.haskell.org\ghc-mod and a few more

Seems to be some Admin issues since when I launch the Atom as Admin the issue is gone.

Atom Version: 1.6.2 System: Microsoft Windows 8.1 Pro Thrown From: haskell-ghc-mod package, v1.12.0

"ghcModPath": "C:\\Users\\Adam\\AppData\\Roaming\\cabal\\bin" should be "ghcModPath": "C:\\Users\\Adam\\AppData\\Roaming\\cabal\\bin\\ghc-mod.exe" or something. Or you can leave it as default. Readme explicitly states that this is path to executable itself, not a directory.

I missed that bit in the Readme. Issue is now solved. Thank you for the patience.

@MauritiusKlein did you install ghc-mod? Did you accidentally put directory path instead of executable path into 'Ghc Mod Path'? Is your environment setup correctly? If on OSX, try running Atom from terminal. It's all in the readme, either this one or ide-haskell's (sorry about that). Well, some parts are on wiki, but those are linked from readme. Seriously.
