Virtualenv
virtualenv es una herramienta para crear y gestionar entornos de Python aislados. Funciona como un gestor de entornos que proporciona un resolvedor para descubrir binarios de Python adecuados y un sistema para establecer directorios independientes con sus propios binarios y paquetes para evitar conflictos de dependencias.
El proyecto se distingue por un resolvedor de intérpretes especializado que maneja shims de gestores de versiones y requisitos de arquitectura. Utiliza caché de imágenes de solo lectura y caché de datos de aplicaciones para acelerar la creación de nuevos entornos, e incluye una herramienta semilla para controlar la instalación de paquetes base requeridos para la utilidad funcional inicial.
La herramienta cubre una amplia gama de capacidades de gestión de entornos, incluyendo aislamiento de binarios mediante enlaces simbólicos, resolución de dependencias basada en rutas y la generación de herramientas de activación de scripts de shell para configurar sesiones de terminal. También proporciona utilidades para la integración con control de versiones para excluir directorios de entorno de ser rastreados en repositorios.
Features
- Python Package Managers - Creates isolated Python environments to prevent version conflicts between different project dependencies.
- Environment Activation Scripts - Generates platform-specific shell scripts to redirect terminal sessions to the isolated binary path.
- Isolated Environment Managers - Provides a comprehensive system for creating and managing isolated execution spaces to prevent dependency conflicts.
- Python - Installs base tools and libraries into standalone directories without affecting the global system installation.
- Python Development Tools - Sets up isolated workspaces with specific interpreter versions to ensure consistent execution across machines.
- Python Environment Managers - Locates and configures specific Python binaries to tailor the runtime environment to a project's needs.
- Runtime Search Path Manipulation - Implements path-based dependency resolution to ensure local environment packages take precedence over system-wide installations.
- Interpreter Resolvers - Implements a specialized resolver to discover Python binaries by handling shims and architecture requirements.
- Interpreter Discovery - Provides a mechanism to locate valid Python binaries by resolving version manager shims and architecture requirements.
- Base Tool Seeding - Includes a seed tool to ensure new environments are immediately functional with baseline management packages.
- Baseline Package Seeding - Ensures new environments have necessary base tools through a controlled installation of seed packages.
- Seed Package Management - Provides a system for controlling the installation and versioning of base packages required for new environments.
- Package Activation Symlinks - Uses symlinks to create standalone directories containing the Python interpreter for namespace isolation.
- Interpreter Image Caches - Implements read-only image caching of interpreter data to significantly reduce the latency of creating new isolated environments.
- Interpreter Image Caching - Utilizes read-only image caching to significantly accelerate the setup of new isolated Python environments.
- Environment and Package Management - Creates isolated Python environments for projects.
- Virtual Environments - Creates isolated Python environments for project dependencies.
