How to leave/exit/deactivate a Python virtualenv

Question

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:~$ ``` 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 `me@mymachine:~$` is to exit the shell and start a new one. That's kind of annoying. Is there a command to work on "nothing", and if so, what is it? If such a command does not exist, how would I go about creating it?

Accepted Answer

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
```
