07.02 — Pipenv vs uv

Overview

This is a quick housekeeping note: this section was originally recorded using Pipenv, while the rest of the course uses uv. The actual code is identical — only the dependency installation commands differ.

Translation Table

Task	Pipenv	uv
Install all dependencies	pipenv install	uv sync
Add a package	pipenv install langchain	uv add langchain
Run a script	pipenv run python main.py	uv run python main.py
Activate virtual env	pipenv shell	source .venv/bin/activate
Lock file	Pipfile.lock	uv.lock
Config file	Pipfile	pyproject.toml

[!NOTE] uv is the modern, Rust-based Python package manager that's significantly faster than Pipenv. It's the recommended tool throughout the rest of the course. The code, imports, and logic are completely identical regardless of which package manager you use.
