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

<pre><code>$ deactivate
</code></pre>

which puts things back to normal.

I have just looked specifically again at the code for <code>virtualenvwrapper</code>, and, yes, it too supports <code>deactivate</code> as the way to escape from all virtualenvs.

If you are trying to leave an <a href="https://en.wikipedia.org/wiki/Anaconda_(Python_distribution)" rel="noreferrer">Anaconda</a> environment, the command depends upon your version of <code>conda</code>. Recent versions (like 4.6) install a <code>conda</code> function directly in your shell, in which case you run:

<pre><code>conda deactivate
</code></pre>

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

<pre><code>source deactivate
</code></pre>

You can use <code>virtualenvwrapper</code> in order to ease the way you work with <code>virtualenv</code>.

Installing <code>virtualenvwrapper</code>:

<pre><code>pip install virtualenvwrapper
</code></pre>

If you are using a standard shell, open your <code>~/.bashrc</code> or <code>~/.zshrc</code> if you use <a href="https://en.wikipedia.org/wiki/Z_shell#Oh_My_Zsh" rel="noreferrer">Oh My Zsh</a>. Add these two lines:

<pre><code>export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
</code></pre>

To activate an existing virtualenv, use command <code>workon</code>:

<pre><code>$ workon myenv
(myenv)$
</code></pre>

In order to deactivate your virtualenv:

<pre><code>(myenv)$ deactivate
</code></pre>

Since the <code>deactivate</code> function created by sourcing <code>~/bin/activate</code> cannot be discovered by the usual means of looking for such a command in <code>~/bin</code>, you may wish to create one that just executes the function <code>deactivate</code>.

The problem is that a script named <code>deactivate</code> containing a single command <code>deactivate</code> will cause an endless loop if accidentally executed while not in the venv. A common mistake.

This can be avoided by only executing <code>deactivate</code> if the function exists (i.e. has been created by sourcing <code>activate</code>).

Using the <code>deactivate</code> feature provided by the venv's <code>activate</code> script requires you to trust the deactivation function to be properly coded to cleanly reset all environment variables back to how they were before— taking into account not only the original activation, but also any switches, configuration, or other work you may have done in the meantime.

It's probably fine, but it does introduce a new, non-zero risk of leaving your environment modified afterwards.

However, it's not technically possible for a process to directly alter the environment variables of its parent, so we can use a separate sub-shell to be absolutely sure our <code>venv</code>s don't leave any residual changes behind:

<hr>

<h2>To activate:</h2>

<code>$ bash --init-file PythonVenv/bin/activate</code>

<ul>
<li>This starts a new shell around the <code>venv</code>. Your original <code>bash</code> shell remains unmodified.</li>
</ul>

<h2>To deactivate:</h2>

<code>$ exit</code> OR <code>[CTRL]</code>+<code>[D]</code>

<ul>
<li>This exits the entire shell the <code>venv</code> is in, and drops you back to the original shell from before the activation script made any changes to the environment.</li>
</ul>

<hr>

<h2>Example:</h2>

<pre><code>[user@computer ~]$ echo $VIRTUAL_ENV
No virtualenv!

[user@computer ~]$ bash --init-file PythonVenv/bin/activate

(PythonVenv) [user@computer ~]$ echo $VIRTUAL_ENV
/home/user/PythonVenv

(PythonVenv) [user@computer ~]$ exit
exit

[user@computer ~]$ echo $VIRTUAL_ENV
No virtualenv!
</code></pre>

I use <a href="https://github.com/Tarrasch/zsh-autoenv" rel="nofollow noreferrer">zsh-autoenv</a> which is based off <a href="https://github.com/kennethreitz/autoenv" rel="nofollow noreferrer">autoenv</a>. 

<blockquote>
 <a href="https://github.com/Tarrasch/zsh-autoenv" rel="nofollow noreferrer">zsh-autoenv</a> automatically
 sources (known/whitelisted) <code>.autoenv.zsh</code> files, typically used in
 project root directories. It handles "enter" and leave" events,
 nesting, and stashing of variables (overwriting and restoring).
</blockquote>

Here is an example:

<pre><code>; 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%s\e[0m\n" "Development tree utiles"
workon dtree
# eof
dtree(feature/task24|✓); cat .autoenv_leave.zsh 
deactivate
</code></pre>

So when I leave the <code>dtree</code> directory, the virtual environment is automatically exited.

<code>"Development tree utiles"</code> is just a name… No hidden mean linking to the Illuminati in here.

For my particular case, I go to to the working directory
<pre><code>CD /myworkingdirectory

Then I activate my env like this:
<pre><code>my-env/scripts/activate

From this same working folder (<code>/myworkingdirectory</code>) to deactivate, I tried this but it does nothing:
<pre><code>my-env/scripts/deactivate
</code></pre>
This does work:
<pre><code>deactivate

I my case, I was able to activate virtual environment using <code>env-name\scripts\activate</code> and deactivate it using <code>deactivate</code>. However, after running update on my windows PC <code>deactivate</code> was no longer recognized as an internal or external command. What I used from that moment onward is <code>env-name\scripts\deactivate</code> and that solved the problem.

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

Example:

<pre><code>#! /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

# Deactivate/switch back to initial interpreter
deactivate()

# Print list of initial environment pip packages for example purpose
import pip
print str(pip.get_installed_distributions())
</code></pre>

I am not 100% sure if it works as intended. I may have missed something completely.

I'm using virtualenv and the virtualenvwrapper. I can switch between virtualenv's just fine using the <code>workon</code> command.
<pre><code>me@mymachine:~$ workon env1
(env1)me@mymachine:~$ workon env2
(env2)me@mymachine:~$ workon env1
(env1)me@mymachine:~$ 
</code></pre>
How do I exit all virtual environments and work on my system environment again? Right now, the only way I have of getting back to <code>me@mymachine:~$</code> is to exit the shell and start a new one. That's kind of annoying. Is there a command to work on &quot;nothing&quot;, and if so, what is it? If such a command does not exist, how would I go about creating it?
