title: Can't find PHP interpreter in PHPStorm
body: <p>I am on Mac OS, and installed PHP5.4, php54-mcrypt, and php54-xdebug using Homebrew. The PHPStorm version is 7.1.3. The executable are located in /usr/local/bin, which are listed as so</p>
  
  <pre><code>angelas-mbp:bin angelawang$ pwd
  /usr/local/bin
  angelas-mbp:bin angelawang$ ls -l | grep php

  <p>However, when entering '/usr/local/bin' or '/usr/local/Cellar/php54/5.4.27/bin', PHPStorm can not find the PHP interpreter.</p>
