title: pyinstaller No module named pyinstaller
body: <p>I have 2 python versions installed under my mac osx sierra:
  python 3.5
  python 2.7</p>
  <p>I installed pyinstaller under python3.5 with this command:</p>
  <pre><code>python3.5 -m pip install pyinstaller
  </code></pre>
  <p>If I run again the same command I'm getting:</p>
  <p>Requirement already satisfied: pyinstaller in ./lib/python3.5/site-packages
  Requirement already satisfied: setuptools in ./lib/python3.5/site-packages (from pyinstaller)</p>
  <p>That to me means that is  is installed under python 3.5 and ready to be used.</p>
  <p>When I run this command:</p>
  <pre><code>python3.5 -m pyinstaller mypython35script.py
  </code></pre>
  <p>I'm getting:
  /Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5: No module named pyinstaller</p>
  <p>Why? What I'm doing wrong?</p>
