uv

To run a Python script with project dependencies using uv, execute the command `uv run python script.py`, which ensures the script runs within the project's specific environment. This provides consistent and reproducible builds without manual virtualenv activation.

Using uv as a drop-in replacement for pip, pip-tools, and virtualenv is a highly effective way to manage reproducible Python environments. It unifies dependency management and environment creation, ensuring consistent builds across different setups.

To add a new dependency to your Python project with uv, use the `uv add` command, which automatically updates the project environment and lockfile. You can then use `uv sync` to ensure all dependencies are correctly installed and synchronized.

Yes, you must install and configure the uv package manager separately before using it to run Python files. Once installed, uv provides the necessary infrastructure to manage and execute project-specific dependencies seamlessly.

Yes, you can use uv in existing Python projects by running `uv sync` to install dependencies from the project's configuration. This allows you to replace pip and pip-tools while maintaining reproducible environments for your current codebase.

UV requires the `uv run` command to execute Python files because it needs to inject the project's specific dependencies into the execution environment. This strict usage rule ensures that the script runs with the exact dependencies defined for the project, guaranteeing reproducibility.
