pip

Use this skill for Python dependency management with safe defaults and reproducible results.

Scope

• Create and maintain project-local virtual environments
• Install, upgrade, uninstall, and inspect Python packages
• Manage requirements.txt and lock-like pinned outputs (pip freeze)
• Troubleshoot common pip failures (externally-managed-environment, resolver conflicts, wheel/build failures)

Safety Defaults

• Prefer isolated installs:
  • project: python3 -m venv .venv
  • app CLI: pipx (if available)
• Avoid global installs unless user explicitly asks.
• Prefer python3 -m pip ... instead of bare pip to avoid interpreter mismatch.
• Never run unknown setup.py or arbitrary install scripts without explicit user approval.

Fast Path

# Initialize venv once per project
python3 -m venv .venv
. .venv/bin/activate
python3 -m pip install --upgrade pip

# Install deps
python3 -m pip install -r requirements.txt

# Pin exact versions
python3 -m pip freeze > requirements.txt

Common Operations

# Install one or more packages
python3 -m pip install requests pydantic

# Upgrade specific package(s)
python3 -m pip install --upgrade requests

# Uninstall package
python3 -m pip uninstall -y requests

# Show package details
python3 -m pip show requests

# List outdated packages
python3 -m pip list --outdated

Reproducible Dependency Flows

# Install from lock-like file
python3 -m pip install -r requirements.txt

# Generate pinned snapshot
python3 -m pip freeze > requirements.txt

# Export JSON metadata for automation
python3 -m pip list --format=json

Troubleshooting

• externally-managed-environment:
  • Use a venv (python3 -m venv .venv) and retry inside it.
  • If user asked for app CLI install, prefer pipx install <tool>.
• No matching distribution found:
  • Check Python version compatibility.
  • Check package name/version typo.
  • Try python3 -m pip index versions <pkg> when available.
• Build/compile failure:
  • Upgrade build tooling: python3 -m pip install -U pip setuptools wheel
  • Install system headers/toolchain if needed, then retry.

Helper Script

Use the bundled helper for repeatable flows:

{baseDir}/scripts/pip-safe.sh detect
{baseDir}/scripts/pip-safe.sh ensure-venv .venv
{baseDir}/scripts/pip-safe.sh install --venv .venv -- requests pydantic
{baseDir}/scripts/pip-safe.sh requirements --venv .venv requirements.txt
{baseDir}/scripts/pip-safe.sh freeze --venv .venv > requirements.txt

Decision Rules

• If task is project dependencies: use venv + pip.
• If task is standalone CLI tool install for a user: suggest pipx first.
• If system policy blocks global installs: stay in venv and explain why.
