  <p>I am trying to install use sqlalchemy inside a virtualenv. I also have python=2.7.14, pip=9.0.1, setuptools=38.2.5 and <strong>the supposed installed sqlalchemy=1.2.0</strong>. I used supposed because when I try upgrading and checking the version of sqlalchemy and flask-sqlalchemy, my computer shows that it's installed but I can't use it.</p>
  
  <p>Here's what I get when I print out sys.path</p>
  
  <pre><code>['', '/usr/lib/python2.7',
