title: Installing to virtual env doesn't work
body: <p>I install to virtualenv, yet it still runs the versions from C:\Python27\site-packages or C:\Python34\site-packages.  When I try to install with pip in my venv I get already installed and the location is the global site-packages.</p>
  
  <p>Any idea why that could be??</p>
  
  <p>Also my virtualenv wrapper commands work but when i do workon X it doesn't activate the venv.  </p>
  
  <p>OS is win7.  But the problem occurred on powershell and git bash.</p>
  
  <p>Thanks</p>
