<div>What version of Stack are you using (stack --version), and how did you install Stack and GHC?</div>
<div><br /></div>
<div>It looks like you're using a system-wide GHC installation, which (for reasons like this) we by default no longer use by default in recent Stack releases.</div>
<div><br /></div>
<div>Upgrading to the latest Stack (via `stack upgrade` or following the instructions at [1]) will probably solve the problem.<br /></div>

<div>I was trying to use Parsec and imported Text.ParserCombinators.Parsec. I could call “stack ghc” to compile the file, but when I loaded the file into ghci and called any function, ghci would report errors</div>

<div>I tried to install transformers by calling `stack install transformers` but the problem still persisted. Is it because the version of transformers in my repo is different from the one referenced by `mtl` package? How should I fix it?</div>
