title: virtualenv python - using Pydev with Eclipse neon
body: <p>So I've just hit the wall and seemingly not making any progress on this issue.
  I just created a virtualenv called test by using Python 3.5's venv. I can activate it from terminal window and deactivate it. So far so good. I also see that the python interpreter in test/bin is actually a symbolic link to my original python 3.5 installation under /Users/LV/anaconda/bin/python3.5</p>
  
  <p>My question is I want to work on a project and keep its site-package folder separate from other projects. I use Eclipse and Pydev. So I created a sample project and when I try to change the python interpreter to test/bin/python, the fact that it is a symbolic link, it gives me an error that I can't use the same interpreter twice. Fine, I don't really care about the interpreter but the problem is all packages under site-packages under my original python installation are still available to me. Where do I tell it that I need to start fresh with external packages and not necessarily use the existing ones? What am I doing wrong?</p>
  
  <p>Thanks much</p>
