You may have a requirement for development on various versions of Python.
Or you may have a mixture of installations including pyenv, custom installations,
system installations etc. Pynball can make leveraging such environments a lot easier.

## Features

---

-   Consolidates all Python installations including [**pyenv**][pyenv-url] into one management system
-   Easily create Virtual Environments using any Python version.
-   Track which virtual environments have which Python versions and tox versions.
-   Quickly change the System interpreter

## Pre Installation Requirements

---

#### Minimum Requirements

1. Python 3.8+
2. [**pipx**][pipx-url]
3. [**Virtualenv**][virtualenv-url] (which has benefits over venv)
4. [**Virtualenvwrapper**][virtualenvwrapper-url]

#### For Maximum Benefits additionally install the following:

1. [**pyenv**][pyenv-url]

## Installation

---

**OS X & Linux:**

Will be supported in version 2

**Windows:**
