When I installed stack by brew and setup for haskell learning, error was occurred

$ which iconv
/Users/{myAccountName}/.pyenv/shims/iconv
Maybe I think which iconv 's output must be /usr/lib, but it is not. That's why I wrote the which iconv callback and ask someone who knows how to change iconv 's callee.
But it is my guess. It was probably not the reason of the error. So, I also ask the other reason of the error and how to fix.
Sorry for not fluent english.
