What is PDM? A new option for Python package management
Hi, I'm Jon. Python is a very popular programming language used by many developers. However, when managing a Python project, installing packages (similar to software components) and managing dependencies (connections to other packages) can be tedious. This is where PDM comes in. PDM is a modern package manager for managing Python packages and dependencies more intelligently, and it follows the latest Python standards (PEP standards). In this article, I'll explain the basics of PDM and the latest updates in an easy-to-understand manner, even for beginners.

Key Features and Benefits of PDM
PDM was developed as an alternative to official Python tools like pip and virtualenv. While pip is a basic tool for installing packages, managing environments for each project can be complicated. PDM, on the other hand, centrally manages project dependencies in a file called pyproject.toml and automatically handles virtual environments (independent Python execution environments for each project). This prevents interference between different projects and allows for smooth development.
Here are some benefits of PDM:
- Support for the latest PEP standards: PEP (Python Enhancement Proposals) is a standard for proposing improvements to Python, and PDM supports them in the latest version. For example, you can use pyproject.toml to standardly describe package configuration.
- Fast dependency resolutionWhen multiple packages depend on each other, PDM efficiently coordinates versions, reducing installation errors.
- Automated management of virtual environments：Automate the creation and switching of virtual environments for each project. You can set up the environment with just one command.
- Easier script execution: Scripts within a project can be easily executed, improving development efficiency.
For example, with PDM, you can initialize a project with "pdm init" and add dependencies with "pdm add package name." This is more intuitive than traditional tools. As of 2025, PDM is actively developed on GitHub and has been updated to support the latest PEP standards since January 2023.
When considering introducing such tools, document creation tools that utilize AI are also useful. For example, a tool called Gamma can instantly create documents and slides using AI. It will be useful when you want to create materials summarizing how to use PDM. For more information,This article .
How to install PDM
Getting started with PDM is easy. Simply run "pip install pdm" from the command line in an environment where Python is installed. According to a guide published by Better Stack in March 2025, after installing PDM, you can smoothly manage virtual environments and control Python versions. Beginners should refer to the official documentation (pdm-project.org).
2025 PDM Latest News and Updates
PDM version 2.0 was released in July 2022, adding built-in virtual environment support, eliminating the need to install a separate virtualenv. This release became a hot topic in the Python community on Reddit, with many developers praising it for making dependency management easier.
As of 2025, a Medium article (September 2025) lists PDM as one of the "Top 5 Package Managers Replacing Pip." The article praises PDM for its speed and compliance with standards, highlighting its potential as a key driver of Python market growth in 2025 (OpenPR reports predict the Python package software market will reach $15 billion by 2033). Additionally, a PDM cheat sheet (Medium) published in December 2024 provides a summary of commands that are still useful as of 2025.
Furthermore, Real Python's June 2025 news reported the beta release of Python 3.14 and mentioned that tools like PDM are evolving to support these new features (new PEPs). Meanwhile, a guide (Medium) from April 2025 for a similar tool called Poetry discussed its user-friendliness compared to PDM, but PDM's strengths lie in the speed of its dependency resolver.
Posts on X (formerly Twitter) also show Python developers talking about the benefits of PDM. For example, they praise its ability to avoid dependency conflicts and its automation of virtual environments. Based on these trends, 2025 is likely to be a year in which PDM becomes even more widespread.
Comparison with competing PDM tools
Competitors to PDM include Poetry and Pipenv. Poetry was described as "user-friendly" in an April 2025 article and features simpler commands than PDM. Meanwhile, PDM was praised in a 2021 Hacker News discussion (updated and relevant in 2025) as a tool that solves the Python packaging "dumpsterfire." Try them out to choose one based on the size of your project and your preferences.
- PDM Strengths: Fast dependency resolution and full PEP compliance.
- The Strengths of Poetry:Intuitive interface.
- Common Benefits: Both use pyproject.toml and are powering the Python ecosystem in 2025.
Tips for utilizing PDM
Tips for using PDM effectively:
- Run "pdm init" at the start of the project.
- To add a dependency, use "pdm add" and specify the version.
- To run the script, use "pdm run".
- For updates, please use "pdm update" regularly.
Now you can efficiently manage your modern Python projects in 2025. Market forecasts (OpenPR, 2025) also show that the demand for such tools is on the rise.

Jon's Summary
PDM is a tool that makes Python development smarter, and is recommended for beginners and intermediate developers alike. The latest updates make dependency management even easier, making it a trend-setting choice for 2025. Try it out with a small project first and experience the joy of development.
