title: Could not find module `Control.Parallel'
body: <p>I'm following <a href="https://wiki.haskell.org/Haskell_in_5_steps#:%7E:text=Haskell%20a%20shot.-,Start%20Haskell,WinGHCi%20in%20the%20Start%20menu.&amp;text=And%20you%20are%20presented%20with%20a%20prompt." rel="nofollow noreferrer">this</a> guide and I got to the &quot;Write your first parallel Haskell program&quot;, where you have you use <code>Control.Parallel</code>. When i try to compile it, I get:</p>
  <pre><code>    A.hs:1:1: error:
      Could not find module `Control.Parallel'
      Use -v (or `:set -v` in ghci) to see a list of the files searched for.
    |
  1 | import Control.Parallel
    | ^^^^^^^^^^^^^^^^^^^^^^^
  </code></pre>
  <p>Nowhere does it say that I have to install anything. Despite that, I ran <code>cabal install --lib parallel</code> and it installed okay but It still cannot find the package. When I run <code>ghc-pkg list</code> <code>parallel</code> is not on the list.</p>
  <p>How do I go about solving that?</p>
