I am getting a similar error with Atom 1.8.0 and the following installed packages:

autocomplete-haskell@0.6.5
haskell-ghc-mod@1.14.6
ide-haskell@1.6.5
ide-haskell-cabal@1.4.0
ide-haskell-repl@0.0.23
language-haskell@1.7.17
open-recent@5.0.0
open-terminal-here@2.1.4

[lierdakil]

Sanity check: did you install ghc-mod?
https://github.com/atom-haskell/ide-haskell#requirements

I need full logs to debug this (or frankly any other) issue. When Atom
reports an error, there's a clipboard icon next to 'View Issue'. Click it,
that will copy report text to clipborad, and then paste it here. Beware,
some low-sensetivity private information might be included (like system
paths, project names, module names, possibly some types).

Sanity check: did you install ghc-mod?

Yes, but I have not tested it alone first. ghc-mod is not working. Sorry for the noise.

[jjohnson382]

I'm getting a similar error and I deciphered my error message to be communicating

ghc-mod: <command line>: cannot satisfy -package-id aeson-0.9.0.1-e2091dbe652be71b5246681ed5c1a48b: 
    aeson-0.9.0.1-e2091dbe652be71b5246681ed5c1a48b is unusable due to missing or recursive dependencies:

[LoranceChen]

Also meet similar trouble. I'm use stack to build my project, with command stack exec atom can avoid this problem.
Hope can support some help to the problem.

[lierdakil]

Carefully read https://github.com/atom-haskell/haskell-ghc-mod/wiki/Using-with-stack. TL;DR: run stack build ghc-mod in your project directory; then make sure 'Stack Sandbox' is enabled in haskell-ghc-mod settings.

Also, make sure you're running at least Atom 1.8.0 and latest haskell-ghc-mod and ide-haskell packages. Old versions are not supported.

Please open new issues with detailed traces if you require help.

[buggymcbugfix]

This works, but remember to make sure you set the path to ghc mod to default:

If you enable 'Stack Sandbox' in haskell-ghc-mod settings (enabled by default), and leave 'Ghc Mod Path' as default ghc-mod (i.e. no actual path), Atom should automatically pick up local stack installation.

[VitaliZaharenko]

1. I've just created a new project with stack new and got this error.
2. A couple of days before, I created an other project in the same way, and all worked fine. It was the only one difference. Stack created old project with lts-8.2, but the new one with lts-8.3. I tried to change version in stack.yaml to resolver: lts-8.2 and I've deleted lts-8.3 folder in .stack-work in a project folder, but error is still here.

@VitaliZaharenko, long story short, run stack build ghc-mod inside the project. Cabal-install and stack don't mix well. There is some movement towards automating that on ghc-mod side, but it's painfully slow-going, I'm sorry to say. So for now you'll have to do that manually.

[VitaliZaharenko]

Yes, this works. Thanks!

This also happens with ghc-mod and ghc-modi installed via stack install and using cabal newbuild.

The problem might be that the parent directory contains a stack project, and ghc-mod seems to search parent directories? I used cabal newbuild for a standalone project and didn't experience the same problems.

##edit

nevermind, apparently ghc-mod just always expect the current project to be a stack project.
