It would appear you're missing binary dependencies. Please refer to https://atom-haskell.github.io/installation/installing-binary-dependencies/

In particular, you need to build ghc-mod.

TL;DR: if using Stack, run stack build ghc-mod in your project root. If using Cabal, create sandbox, install ghc-mod there and add sandbox's bin directory to 'Additional Path Directories'.

i dont know what stack is or cabal , i dont know what sandbox is can you explain in more detail please? i put on terminal the following command: apm install language-haskell ide-haskell ide-haskell-cabal haskell-ghc-mod autocomplete-haskell then i got these: Installing language-haskell to /root/.atom/packages ✓ Installing ide-haskell to /root/.atom/packages ✓ Installing ide-haskell-cabal to /root/.atom/packages ✓ Installing haskell-ghc-mod to /root/.atom/packages ✓ Installing autocomplete-haskell to /root/.atom/packages ✓

Atom-Haskell packages have binary dependencies that can not be installed with apm. Follow the link provided in my previous comment, then read carefully. Especially warnings. The guide assumes you have at least a basic idea of what you're doing, hence minimal knowledge on the Haskell ecosystem is required. You can start off with https://www.haskell.org/downloads (which you need to get compiler and toolchain anyway)

Closing due to inactivity.
