title: Python module is imported on terminal but not on IDLE
body: <p>I use python 3.6.4 and my OS is macOS High Sierra.</p>
  
  <p>So I've installed <code>pynput</code>. I can import it well on terminal, however, not on Python IDLE.

  <p>I've used <code>sys.version</code> &amp; <code>sys.path</code> and they're the same. I only have python 3.6 installed on my Mac
