Solved haskell intellij-idea ghc ghc-mod

I just installed IntelliJ idea and the official Haskell plugin. IntelliJ couldn't find ghc-modi.exe, so I installed ghc-mod through cabal.

However, after importing my cabal project, I am still receiving the following error:

ghc-modi failed with error: NG BUG: GMECabalFlags (GMEString "extractField: failed extracting configFlags from input, input contained `configFlags'? False")

How can I solve or get more information on this error?

Thanks in advance.

There is an incompatability with cabal 1.22, GHC 7.8 and the currect ghc-modi. You should downgrade to cabal 1.20 or upgrade to GHC 7.10 and it should fix the issue. – Informal 13/2, 2015 at 16:40

This question has been answered by Atsky on GitHub:

This is internal problem of ghc-mod. It fails to read file dist/setup-config for some reason. Try to remove dist folder from your project and then run cabal config.
