I defined an alias workoff as the opposite of workon:

alias workoff='deactivate'

Easy to remember:

[bobstein@host ~]$ workon django_project

(django_project)[bobstein@host ~]$ workoff

[bobstein@host ~]$

$ 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 as a compliment/counterpart to source activate. YMMV

to activate python virtual environment:

$cd ~/python-venv/

$./bin/activate

to deactivate:

$deactivate

You can use virtualenvwrapper in order to ease the way you work with virtualenv

Installing virtualenvwrapper

pip install virtualenvwrapper

If you are using standard shell, open your ~/.bashrc or ~/.zshrc if you use oh-my-zsh. Add this two lines:

export WORKON_HOME=$HOME/.virtualenvs  

source /usr/local/bin/virtualenvwrapper.sh

To activate an existing virtualenv, use command workon:

$ workon myenv

(myenv)$

In order to deactivate your virtualenv:

(myenv)$ deactivate

Here is my tutorial, step by step in how to install virtualenv and virtualenvwrapper

I use zsh-autoenv which is based off autoenv.

zsh-autoenv automatically
sources (known/whitelisted) .autoenv.zsh files, typically used in
project root directories. It handles "enter" and leave" events,
nesting, and stashing of variables (overwriting and restoring).

Here is an example:

; cd dtree 

Switching to virtual environment: Development tree utiles

;dtree(feature/task24|✓); cat .autoenv.zsh       

# Autoenv.

echo -n "Switching to virtual environment: "

printf "e[38;5;93m%se[0mn" "Development tree utiles"

workon dtree

# eof

dtree(feature/task24|✓); cat .autoenv_leave.zsh 

deactivate

So when I leave the dtree directory, the virtual environment is automatically exited.

(my_env) basant@basant:~/EonTraining/my_env$ deactivate

use 'deactivate'

basant@basant-Lenovo-E40-80:~/EonTraining/my_env$

Gone (my_env);

Had the same problem myself while working on an installer script, I took a look at what the bin/activate_this.py did and reversed it.

Example:

#! /usr/bin/python

# -*- coding: utf-8 -*-

import os

import sys



# path to virtualenv

venv_path = os.path.join('/home', 'sixdays', '.virtualenvs', 'test32')



# Save old values

old_os_path = os.environ['PATH']

old_sys_path = list(sys.path)

old_sys_prefix = sys.prefix





def deactivate():

    # Change back by setting values to starting values

    os.environ['PATH'] = old_os_path

    sys.prefix = old_sys_prefix

    sys.path[:0] = old_sys_path





# Activate the virtualenvironment

activate_this = os.path.join(venv_path, 'bin/activate_this.py')

execfile(activate_this, dict(__file__=activate_this))





# Print list of pip packages for virtualenv for example purpose

import pip

print str(pip.get_installed_distributions())

# Unload pip module

del pip



# deactive/switch back to initial interpreter

deactivate()



# print list of initial environment pip packages for example purpose

import pip

print str(pip.get_installed_distributions())

Not 100% sure if it works as intended, I may have missed something completely.
