Pyenv
pyenv is a Python version manager and runtime orchestrator that allows for the installation and switching of multiple Python versions on a single machine without affecting the system installation. It functions as a shell-based version controller that manages binaries through shims to redirect executable calls to specific versions.
The tool is a plugin-extensible system, allowing users to add custom subcommands and logic via shell script plugins. This architecture enables the extension of the command line interface through a dedicated plugins directory.
It provides capabilities for side-by-side installation by building specific versions from source. Version management includes the ability to activate runtimes globally or on a per-project basis, the simultaneous activation of multiple versions, and the removal of installed runtimes.
Features
- Python Version Managers - Installs and switches between different Python versions on a single machine without affecting the system installation.
- Command Interception Shims - Uses lightweight proxy scripts to intercept command calls and redirect them to the correct Python version.
- Runtime Version Managers - Downloads and builds specific Python versions from source based on a list of available releases.
- Path-Based Version Switchers - Switches active Python versions by dynamically modifying the system PATH environment variable.
- Shell-Based - Manages Python binaries through shell integration and shims to redirect executable calls.
- Toolchain Versioning - Allows changing the active Python runtime globally or for specific directories.
- Per-Project Runtime Assignments - Assigns a particular Python version to a specific directory so the correct environment is used for each project.
- Python Runtime Managers - Provides an environment for managing multiple Python installations to test code across different releases.
- CLI Extensions - Adding new subcommands and custom logic to the Python version manager using shell script plugins.
- Plugin Systems - Provides a system for extending core functionality and adding custom subcommands via modular plugins.
- Shell Plugin Architectures - Extends the tool's functionality by executing external shell scripts discovered in a dedicated plugins directory.
- Configuration Cascade Resolutions - Determines the active Python version by cascading settings from the current directory up to the root.
- Plugin-Extensible Runtimes - Implements a version management system that supports custom subcommands and logic via shell script plugins.
- Version Managers - Enables simultaneous activation of several Python versions to search for commands across multiple installations.
- Runtime Builds - Builds specific Python versions from source code to ensure compatibility with the local operating system.
- Isolated Runtime Directories - Organizes multiple Python installations in independent directories to prevent conflicts between different version binaries.
- Side-by-Side Runtimes - Enables the compilation of various Python versions on a single machine without interfering with the system-wide installation.
- Environment Management - Simple Python version management.
- Python Frameworks and Tools - Python version management tool.
