title: Shifting packages between different versions of python
body: <p>My mac has two versions of Python,</p>
  
  <p>one installed in <code>/Library/Frameworks/Python.framework/Versions/2.7/bin/pip</code></p>
  
  <p>and the other <code>/Library/Python/2.7/site-packages/</code></p>
  
  <p>I have plenty of packages installed in the second directory. How do I move all those packages under the first python ?</p>
  
  <p>Also How do I force my mac to use the first Python ?</p>
