title: Virtualenv: deactivate not working
body: <p>I had a venv called "MyAppEnv" that I was using and I tried to write a script I could run that would call <code>source bin/activate</code> (save me some keystrokes). I accidentally ran it while already in MyAppEnv. Since doing this, when I try to deactivate MyAppEnv, I get <code>bash: type: deactivate: not found</code>. This happens even in the brand-new environment I created, totally separate from MyAppEnv. How do I get it back? I cannot exit out of my environment except by killing my screen session. </p>
