How to leave/exit/deactivate a Python virtualenv

Usually, activating a virtualenv gives you a shell function named:

$ deactivate

which puts things back to normal.

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.

If you are trying to leave an Anaconda environment, the command depends upon your version of conda. Recent versions (like 4.6) install a conda function directly in your shell, in which case you run:

conda deactivate

Older conda versions instead implement deactivation using a stand-alone script:

source deactivate

Use:

$ deactivate 

If this doesn't work, try

$ source deactivate

Anyone who knows how Bash source works will think that's odd, but some wrappers/workflows around virtualenv implement it as a complement/counterpart to source activate. Your mileage may vary.

I defined an alias, workoff, as the opposite of workon:

alias workoff='deactivate'

It is easy to remember:

[bobstein@host ~]$ workon django_project
(django_project)[bobstein@host ~]$ workoff
[bobstein@host ~]$

To activate a Python virtual environment:

$cd ~/python-venv/
$./bin/activate

To deactivate:

$deactivate
