Umgebungsvariablen

# Virtualenv location
export PIPENV_VENV_IN_PROJECT=1           # Create .venv in project
export WORKON_HOME=~/.virtualenvs         # Custom virtualenv location

# Timeout settings
export PIPENV_TIMEOUT=300                 # Lock timeout (seconds)
export PIPENV_INSTALL_TIMEOUT=900         # Install timeout

# Behavior settings
export PIPENV_SKIP_LOCK=1                 # Skip lock generation
export PIPENV_NOSPIN=1                    # Disable spinner (for CI)

.env Dateiunterstützung

Pipenv lädt automatisch .env Datei in Projektwurzel:

# .env file example
DATABASE_URL=postgresql://localhost/mydb
SECRET_KEY=your-secret-key
DEBUG=True

Häufige Anwendungsfälle

Use Case: Neues Django-Projekt starten

# Initialize project with Python 3.11
pipenv --python 3.11

# Install Django and production dependencies
pipenv install django psycopg2-binary gunicorn

# Install development tools
pipenv install pytest pytest-django black --dev

# Activate environment and start project
pipenv shell
django-admin startproject myproject .

Use Case: Bereitstellung zur Produktion

# On development machine - lock dependencies
pipenv lock

# Commit Pipfile and Pipfile.lock to version control
git add Pipfile Pipfile.lock
git commit -m "Lock dependencies"

# On production server - install exact versions
pipenv sync

# Run application
pipenv run gunicorn myapp.wsgi:application

Use Case: Arbeiten mit Teammitgliedern

# Clone repository
git clone https://github.com/team/project.git
cd project

# Install all dependencies (including dev)
pipenv install --dev

# Activate environment
pipenv shell

# Run tests
pytest

# When adding new package, lock and commit
pipenv install new-package
git add Pipfile Pipfile.lock
git commit -m "Add new-package dependency"

Use Case: CI/CD Pipeline

# In CI configuration (e.g., .gitlab-ci.yml, GitHub Actions)
# Install pipenv
pip install pipenv

# Install dependencies without dev packages
pipenv sync

# Run tests
pipenv run pytest

# Check for security vulnerabilities
pipenv check

# Set CI-friendly environment variables
export PIPENV_NOSPIN=1
export PIPENV_HIDE_EMOJIS=1

Use Case: Mehrere Umgebungen verwalten

# Development environment
pipenv install --dev
pipenv run python manage.py runserver

# Testing environment
pipenv sync --dev
pipenv run pytest

# Production environment
pipenv sync  # Only production dependencies
pipenv run gunicorn app:app

# Staging with specific configuration
pipenv run --env-file=.env.staging python app.py

oder Best Practices

  • ** verpflichtet immer sowohl Pipfile als auch Pipfile.lock* zur Versionskontrolle für reproduzierbare Builds über Umgebungen
  • Use pipenv sync in der Produktion anstelle von pipenv install_, um genaue Versionen von Pipfile zu gewährleisten. Schloss installiert
  • Separate dev und Produktionsabhängigkeiten mit --dev Flagge, um Produktionsumgebungen schlank zu halten
  • Run pipenv check_ regelmäßig um Sicherheitslücken in Ihren Abhängigkeiten zu scannen
  • **Diese Versionszwänge sinnvoll nutzen* - ~=_ für kompatible Versionen, >=,< für Reichweiten, == nur bei Bedarf **Create virtualenv im Projektverzeichnis* durch Einstellung PIPENV_VENV_IN_PROJECT=1 für eine einfachere IDE-Integration
  • Use pipenv run für Ein-Aus-Befehle statt Shell zu aktivieren, wenn Skripte in der Automatisierung ausgeführt werden
  • Gemeinsame Skripte in Pipfile unter [scripts] Sektion für Teamkonsistenz
  • **Keep Pipfile.lock aktualisiert* durch Laufen __INLINE_CODE_71_ nach Änderung Pipfile manuell
  • Use .env Dateien für die umgebungsspezifische Konfiguration - Pipenv lädt sie automatisch

Fehlerbehebung

Issue Solution
INLINE_CODE_73 Add INLINE_CODE_74 to PATH or reinstall with INLINE_CODE_75
Lock operation takes too long Increase timeout: INLINE_CODE_76 or use INLINE_CODE_77 for faster installs
Dependency resolution conflicts Try INLINE_CODE_78 to regenerate lock file from scratch
Virtual environment not activating Check INLINE_CODE_79 shows path, try INLINE_CODE_80 and recreate with INLINE_CODE_81
Package not found in Pipfile.lock Run INLINE_CODE_82 to regenerate lock file with new dependencies
Wrong Python version used Specify version explicitly: INLINE_CODE_83 or check INLINE_CODE_84 in Pipfile
SSL certificate verification errors Set INLINE_CODE_85 in Pipfile INLINE_CODE_86 section (not recommended for production)
Pipenv installs system-wide packages Ensure INLINE_CODE_87 is not set, or unset it
Can't find locally installed package Install in editable mode: INLINE_CODE_88
INLINE_CODE_89 fails in CI Use INLINE_CODE_90 to ignore specific known issues
Slow package installation Use a PyPI mirror: INLINE_CODE_91
Conflicting lock file on team Ensure all team members use same Python version specified in INLINE_CODE_92
