This module supports virtual environments from conda and virtualenvwrapper. By default, only virtualenvwrapper is enabled. To disable virtualenvwrapper, add the following to *zpreztorc*.
```sh
zstyle ':prezto:module:python' skip-virtualenvwrapper-init 'on'
```
Conda support is enabled by adding the following to *zpreztorc*.
```sh
zstyle ':prezto:module:python' conda-init 'on'
```
Caution: using conda and virtualenvwrapper at the same time may cause conflicts.

(`$VIRTUALENVWRAPPER_VIRTUALENV` is explicitly set or `virtualenv` is in
`$PATH`). This can be disabled with:
```
```sh
zstyle ':prezto:module:python:virtualenv' initialize 'no'
```
On some systems, the `python` binary doesn't exist so in order to get
virtualenvwrapper to work, the path needs to specified. We do our best to detect
this, but sometimes it needs manual intervention.
```sh
zstyle ':prezto:module:python:virtualenvwrapper' python-path /opt/python3/bin/python3
```
