Haskell Stack: installed packages are not visible
<p>I installed package with <code>stack install</code> but I cannot import the package unless I use <code>stack ghc</code> or <code>stack ghci</code> ...</p>

<p>The problem is I have installed <code>atom haskell ide</code>, that uses <code>ghc-mod</code> backend, which also doesn't see packages installed by stack!</p>
