pyenv-latest: A pyenv plugin to make pyenv friendlier

Currently pyenv installs versions that are distinct to the micro version. This makes upgrading local Python installations to the latest version needlessly painful. pyenv-latest adds a new install-latest command to pyenv that will install the latest version of a provided alias. In addition, it will group site-packages together in a folder per minor version so upgrading your Python version will not require you reinstall all your packages and virtual environments.

This plugin only hooks into the existing pyenv install command, so you will see each micro version listed independently when you run pyenv versions. It does not currently uninstall old versions when upgrading.

Currently only standard CPython versions are supported.

Installation

You must have pyenv installed.

Install as a pyenv plugin.

cd $PYENV_ROOT/plugins
git clone https://github.com/akedrou/pyenv-latest.git

Usage

pyenv install-latest 3.7

Status

This project is not meant to be a long-term solution. Ideally this feature will be implemented in the pyenv project and this plugin can peacefully die. That said, it does address an immediate need (however hackily) and so I'm happy to accept submissions.
