<s>[INST] How to leave/exit/deactivate a python virtualenv? I'm using virtualenv and the virtualenvwrapper. I can switch between virtualenv's just fine using the workon command. 
me@mymachine:~$ workon env1
(env1)me@mymachine:~$ workon env2
(env2)me@mymachine:~$ workon env1
(env1)me@mymachine:~$

However, how do I exit all virtual machines and workon my real machine again? Right now, the only way I have of getting back to
me@mymachine:~$

is to exit the shell and start a new one. That's kind of annoying. Is there a command to workon "nothing", and if so, what is it? If such a command does not exist, how would I go about creating it?
 [/INST] Usually, activating a virtualenv gives you a shell function named:
$ deactivate

which puts things back to normal.
Edit: I have just looked specifically again at the code for virtualenvwrapper, and, yes, it too supports "deactivate" as the way to escape from all virtualenvs.
Edit: If you are trying to leave an Anaconda environment, the procedure is a bit different: run the two-word command source deactivate since they implement deactivation using a stand-alone script.
bash-4.3$ deactivate
pyenv-virtualenv: deactivate must be sourced. Run 'source deactivate' instead of 'deactivate'
bash-4.3$ source deactivate
pyenv-virtualenv: no virtualenv has been activated.
