Pdm
PDM 是一个 Python 包管理器、依赖解析器和构建工具，旨在创建可重现的环境。它作为一个运行时管理器，使用独立构建安装和切换不同版本的 Python 解释器，同时管理隔离的虚拟环境以防止项目之间的版本冲突。
该工具通过使用跨平台锁文件和基于插件的扩展架构脱颖而出，允许用户通过外部发行版添加新功能。它提供了一个集中的包缓存系统和并行安装流水线，以减少环境设置和依赖解析所需的时间。
除了核心管理，PDM 还通过自定义脚本定义和命令行快捷方式涵盖项目编排。它还处理完整的发行生命周期，从生成标准化的项目存档到将包发布到远程仓库。
该工具通过使用标准化的元数据格式确保互操作性，并提供用于从其他管理器导入和转换项目配置的实用程序。
Features
- Python Package Managers - Provides comprehensive management of Python project dependencies, virtual environments, and package installations.
- Dependency Lockfiles - Generates cross-platform lockfiles with checksums to ensure reproducible dependency environments.
- Build Reproducibility Lockfiles - Provides cross-platform lockfiles that pin exact dependency versions and checksums for reproducible environments.
- Runtime Provisioning - Downloads and manages standalone pre-compiled Python interpreter builds to decouple projects from system-wide installations.
- Dependency Resolution - Resolves complex version constraints and source repositories to find compatible package versions.
- Python Environment Managers - Creates isolated environments and manages multiple interpreter versions for project-specific dependencies.
- Virtual Environment Managers - Provides isolated runtime environments to prevent dependency conflicts between different software projects.
- Dependency Resolvers - Calculates compatible package versions and generates cross-platform lockfiles to ensure reproducible environments.
- Python Distribution Packaging - Builds and prepares Python projects into standardized distribution archives for publication to registries.
- Virtual Environment Isolation - Creates isolated execution spaces for Python projects to prevent dependency version conflicts.
- Multi-Version Installations - Automatically downloads and installs multiple specific versions of the Python runtime using standalone builds.
- Python Runtime Managers - Installs and manages multiple versions of the Python interpreter using standalone builds.
- Package Dependency Resolution - Implements a constraint-based solver to determine compatible package versions and generate a deterministic dependency graph.
- Build Artifact Caching - Stores decompressed build artifacts locally to speed up dependency resolution and installation cycles.
- Parallel - Employs a parallel installation pipeline to download and install multiple dependencies simultaneously for faster setup.
- Parallel Installations - Implements a parallel installation pipeline to accelerate the setup of project dependencies.
- Environment Managers - Manages isolated runtime environments and language versions to separate package installations.
- Package Caches - Maintains a shared global directory of downloaded distributions to eliminate redundant network requests.
- Project Orchestration - Coordinates the execution of custom project scripts and automation tasks via centralized configuration.
- PEP Standards - Ensures interoperability by mapping project specifications to official Python Enhancement Proposal metadata and packaging standards.
- Remote Repository Publishing - Uploads built distributions to remote repositories using secure authentication and trusted publishing mechanisms.
- Project Metadata Specifications - Uses standardized project metadata specifications to define build requirements and ensure tool interoperability.
- Environment Synchronizers - Aligns the currently installed packages in an environment to match the exact versions specified in a lockfile.
- Distribution Package Generators - Generates standardized distributable archives from source directories to prepare projects for remote publication.
- Platform Extension Plugins - Provides an extensible plugin system that allows users to share and integrate custom distributions.
- Interpreter Switching - Allows users to toggle between different active Python interpreter versions.
- Plugin Installation and Management - Installs and organizes project-specific extensions to add modular capabilities to the environment.
- Plugin-Based Architectures - Features a modular extension architecture that allows adding new capabilities via external plugin distributions.
- 开发者工具 - Modern package and dependency manager.
- Package Managers - Modern package manager supporting current packaging standards.
