Installation

PyRCS can be installed via uv (recommended for speed, reliability and modern dependency resolution), pixi, traditional pip or conda-forge.

Using uv (Recommended)

uv is a fast Python package installer and project manager written in Rust.

Adding to a uv project

To add the latest release of PyRCS to your existing project managed by uv:

> uv add pyrcs

Installing in a virtual environment

If you are working inside an active virtual environment and wish to install PyRCS directly using uv pip:

> uv pip install --upgrade pyrcs

To install the latest development version directly from GitHub:

> uv pip install --upgrade git+[https://github.com/mikeqfu/pyrcs.git](https://github.com/mikeqfu/pyrcs.git)

Using pixi

pixi is a modern package management tool built on top of conda-forge.

Adding to a pixi project

To add the core PyRCS package to a workspace using pixi:

> pixi add pyrcs

Alternatively, to install PyRCS with PyPI extras inside a pixi project:

> pixi add --pypi pyrcs

Installing globally

To install PyRCS as a globally accessible tool via pixi:

> pixi global install pyrcs

Using pip

If you prefer standard Python packaging tools, ensure your virtual environment is activated and use pip install:

> pip install --upgrade pyrcs

To install the development version from GitHub:

> pip install --upgrade git+https://github.com/mikeqfu/pyrcs.git

Note

• For general guidelines on Python virtual environments and dependency management, refer to the Python Packaging User Guide.

Using conda or mamba

PyRCS is published on conda-forge and can be managed using conda or mamba.

Installing the core package

To install PyRCS into an active environment using conda:

> conda install -c conda-forge pyrcs

Or, using mamba:

> mamba install -c conda-forge pyrcs

Verification

To verify the installation, import the package in a Python interpreter shell:

>>> import pyrcs
