Huak - A Python Package manager written in Rust

Do you have a good reason for using huak-specific tables for storing project metadata and dependencies in pyproject.toml when you can use the normal project metadata specification? https://packaging.python.org/en/latest/specifications/declaring-project-metadata/ If PEP621 is insufficient, I'd recommend making it clear in the README, otherwise you might invite the impression that you're not too familiar with python packaging standards.

Comparing Package Management in Python, R, Julia, and Rust

May 25, 2024 - Create an environment with python -m venv /path/to/environment. R: renv manages project-specific environments. Create an environment with renv::init(project = "path/to/environment") . Julia: Environments are managed within the Pkg module. I have a blog post about Julia environments. Create an environment with Pkg.activate("path/to/environment"). Rust: Environments are handled within cargo projects, use cargo new my_project. When you release and distribute your package it's good to be aware of how it's handled by the package repository and package manager.

Introduction - PyO3 user guide

To run this all as a single copy-and-paste, use the bash script below (replace string_sum in the first command with the desired package name): mkdir string_sum && cd "$_" python -m venv .env source .env/bin/activate pip install maturin maturin init --bindings pyo3 maturin develop · If you want to be able to run cargo test or use this project in a Cargo workspace and are running into linker issues, there are some workarounds in the FAQ. As well as with maturin, it is possible to build using setuptools-rust or manually.

r/rust on Reddit: Started work on a new python package manager this time in Rust

March 1, 2022 -

https://github.com/Lioncat2002/FerryRecently got into Rust programming and thought this would be a good project

this is essentially a rewrite of CBreeze python package manager which I wrote in C++ which was unfortunately limited to linux only and a few other short comings.

Hopefully in this rewrite I will be root out those caveats.I will keep this thread updated as regularly as I can.

Change Log:

Version Ferry-0.0.2-alpha:- Better cli and a run command

Version Ferry-0.0.1-prealpha:-Added the ability to install packages without needing to manually activate the virtual environment.

Version Ferry-0.0.0-prealpha:- Ability to fetch packages from PyPI

- Ability to create a new project complete with a virtual environment(WIP)

- Can run on windows(need to work on the project creation command on linux)

Can I contribute to this? This is exciting!

r/Python on Reddit: Huak - A Python Package manager written in Rust

September 16, 2022 -

Hi! I started Huak to build a package manager focusing on making Python projects more approachable by offering a standardized workflow.

https://github.com/cnpryer/huak

You do need the rust toolchain installed if you want to install huak during the PoC phase. Either way any feedback is appreciated.

If you're also a long time Python dev that enjoys package managers feel free to reach out. I'd love to chat about your preferences.

Do you have a good reason for using huak-specific tables for storing project metadata and dependencies in pyproject.toml when you can use the normal project metadata specification? https://packaging.python.org/en/latest/specifications/declaring-project-metadata/ If PEP621 is insufficient, I'd recommend making it clear in the README, otherwise you might invite the impression that you're not too familiar with python packaging standards.

Use Rust's Speed to Install Python Libraries Up to 100 Times Faster | Towards Data Science

January 24, 2025 - To achieve its blazing speed, it was built in Rust. Additionally, it was designed as a drop-in replacement for pip and pip-tools workflows. That sounds promising! Before putting it to the test, let’s briefly briefly touch upon the difference between an installer and resolver: package installers (e.g., pip) are used to install, update, and remove Python packages from our environment.

From the makers of ruff comes uv

TL;DR: uv is an extremely fast Python package installer and resolver, written in Rust, and designed as a drop-in replacement for pip and pip-tools workflows.

It is also capable of replacing virtualenv.

With this announcement, the rye project and package management solution created by u/mitsuhiko (creator of Flask, minijinja, and so much more) in Rust, will be maintained by the astral team.

This "merger" and announcement is all working toward the goal of a Cargo-type project and package management experience, but for Python.

For those of you who have big problems with the state of Python's package and project management, this is a great set of announcements...

For everyone else, there is https://xkcd.com/927/.

GitHub

Install it today:

pip install uv
# or
pipx install uv
# or
curl -LsSf https://astral.sh/uv/install.sh | sh

no fucking way now do a drop-in replacement for mypy as well, and my entire python toolkit will be handled by the same party pkg mgmt + lint + format + type checks

It still seems to me that poetry is the closest to cargo like experience and after working extensively with pip-compile I can only say that I don’t want any replacement for that. I want to forget the bad experience with pip-tools altogether, it’s the worst. But if there was a rust rewrite of poetry, that was fast and provided the same level of convenience, I believe that could move the mess of Python dependency management forward. But perhaps dropping pip-tools in favor of uv would improve my experience as well, as a sort of stepping stone.

python - Issue with installing packages with pip: "Cargo, the Rust package manager, is not installed or is not on PATH" - Stack Overflow

Try installing the tooling for the Rust programming language, because it seems like you have a dependency that uses Rust.

For mac OS, I recommend using brew.

brew install rust

Otherwise use the steps from the Rust install page.

You can check that rust is installed properly with:

rustc --version

Once you are finished try again to pip install your requirements file.

I had the same issue with the docker image python:3.12-alpine. This answer was the first one I found. When I tried to install the rust compiler on the alpine container, my pip package (solana dependency - solders) took forever to compile. The only solution I found was to use python:3.12-bookworm instead. It didn’t require any compilation or rust installation. It just worked out of the box. I hope my answer helps someone save a few evenings.

How to Use UV Package Manager for Python Projects

February 17, 2026 - This combination of speed, simplicity, and compatibility makes UV a practical alternative to pip and poetry for everyday Python development. Traditional tools like pip are often criticized for being slow and inefficient, especially when managing large projects. UV addresses these issues by leveraging Rust’s performance capabilities. For example: Speed: UV can install packages up to 100x faster than pip when using a warm cache.
