history

Project history and usage

pyenv-virtualenv is a pyenv plugin for creating, listing, activating, and deleting virtualenv, venv, and Conda environments on Unix-like systems.

Project history

pyenv-virtualenv emerged in the early pyenv ecosystem as a plugin for creating and selecting isolated environments. Its changelog shows active development from 2013 onward, with automatic activation introduced in 2014 and later support for venv, Conda, Fish, and newer pyenv releases.

Adoption history

The plugin expanded beyond classic virtualenv environments to support Python's standard venv module and Conda environments. It is distributed directly as a pyenv plugin and as a Homebrew formula for macOS users.

How it is used

Create environments with pyenv virtualenv, list them with pyenv virtualenvs, and activate them manually with pyenv activate. With virtualenv-init enabled, entering a directory whose .python-version names an environment automatically activates it.

Why package nerds care

pyenv-virtualenv joins interpreter-version selection and isolated dependency environments without folding either concern into pyenv core. Its directory-triggered activation through .python-version files is especially useful to shell-centric development workflows.

Timeline

2013: Early public releases added environment creation and listing
2014-06-14: Automatic activation support was introduced
2016-07-16: The plugin adopted python -m venv where appropriate
2023: The 1.2 release line modernized integration with Pyenv 2
