SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Establishes a consistent, isolated Python virtual environment at the project root to prevent pollution of the global Python installation and drift across projects.

Core Features & Use Cases

Checks for an existing venv at the project root and reuses it when available.
Creates the venv at <project_root>/venv/ only if missing, ensuring a standard location.
Installs dependencies from a provided requirements.txt and verifies that key packages import correctly.

Quick Start

If no venv exists at the project root, create venv at venv/, then install dependencies from a provided requirements.txt and verify key packages.

FAQPage Schema

How do I isolate Python dependencies to prevent global site-packages pollution?▼

Python dependency isolation is achieved by creating a virtual environment at the project root, which prevents global site-packages pollution and ensures consistent dependency versions.

What is the best way to set up a Python virtual environment using requirements.txt?▼

Setting up a Python virtual environment involves checking for an existing venv at the project root, creating one if missing, and installing dependencies from a requirements.txt file to verify key packages.

Does Python venv setup reuse an existing virtual environment at the project root?▼

Yes, virtual environment setup checks for an existing venv at the project root and reuses it when available. It only creates a new venv if one is currently missing.

Why do I need a project-root virtual environment for Python development?▼

A project-root virtual environment is needed to prevent drift across projects and isolate dependencies. It establishes a standard venv location to verify package imports safely.

Can I verify package imports after installing dependencies in a Python venv?▼

Yes, you can verify package imports after installing dependencies in a Python venv. The setup process explicitly checks that key packages import correctly following installation.

What happens if an existing venv is missing during Python environment setup?▼

If an existing venv is missing during Python environment setup, a new virtual environment is created at venv/ in the project root, followed by dependency installation and import verification.
