# pyenv-win - Poor man's pyenv for Windows
A simple script (both for PowerShell and CMD) that allows to install/uninstall/switch between/manage 64-bit Python 3 versions for Windows provided as binaries by [Python.org](https://www.python.org/downloads/windows/).
The original installers (python-X.X.X-amd64.exe) are never executed, and therefor nothing is written to the Registry, other than updating the Path environment variable (in userspace) when (globally) switching between Python versions.
At the time of writing, 76 different Python versions can be installed, the earliest being 3.5.0 and the latest 3.12.4 (versions 3.4.x and earlier use different installers and are therefor not supported).
## Setup
Run this command in PowerShell:
```
iex (iwr "https://raw.githubusercontent.com/59de44955ebd/pyenv-win/main/install.txt").Content
```
## Usage
```
PS> pyenv
Usage: pyenv []
Available commands:
===================
install Install a Python version (download from python.org)
uninstall Uninstall a Python version
global Change the globally active Python version
(updates environment variables in userspace registry)
local Change the local active Python version
(only for the current CMD or Powershell instance)
versions List all Python versions currently installed via pyenv
list List all Python versions that can be installed
update-list Update the list of installable Python versions available at python.org
pip-transfer Utility, tries to install all packages of version in version
pip-upgrade-all Utility, upgrades all outdated packages for the active Python version
```

## Notes
The tool dark.exe, which is used to extract .msi files from installers (python-X.X.X-amd64.exe) provided by [Python.org](https://www.python.org/downloads/windows/) without actually running the installer, is part of the [WiX Toolset ](https://github.com/wixtoolset/).
