Back UV (Universal Virtual environment) Init Overview 17 Jun, 2025

uv init is a command from the UV package manager, a fast, Rust-based Python package manager and virtual environment manager designed as a modern alternative to pip, pip-tools, and virtualenv.


🔧 What uv init Does:

uv init sets up a Python project with:

  • A new virtual environment.

  • A pyproject.toml file (standard for Python packaging).

  • A .venv/ directory for isolated dependencies.

  • A .gitignore (if Git is initialized).


Benefits:

  • Blazing fast: Written in Rust.

  • Unified: Manages both environments and dependencies.

  • Simple bootstrapping: One command to get started.


🧪 Example Usage:

uv init

After running:

  • Run uv pip install requests to add dependencies.

  • Use uv venv to manage the virtual environment.
