title: Finding modules when running python with virtualenvs, in launchd
body: <p>This Q&amp;A is similar to the one offered in <a href="https://stackoverflow.com/questions/17582975/python-script-not-running-in-crontab-calling-pysaunter/17687950#17687950">Python Script not running in crontab calling pysaunter</a> , but is put in terms of Launchd &amp; Plists.</p>
  
  <p>I was successfully running python scripts in a virtualenv, but when I tried to schedule it in Launchd, I received a traceback error to my plist error log file saying "ImportError: No module named sqlalchemy".  What to do, what to do?</p>
