pip check

Solution: - Pin versions in requirements.txt - Verify plugin compatibility - Unify Python version

Performance Optimization

Image Optimization: 

# Automated WebP conversion
find docs -name "*.png" -exec cwebp {} -o {}.webp \;

Build Acceleration: 

plugins:
  - optimize:
      enabled: !ENV [CI, false]

4.2 Maintenance and Updates

Dependency Update Workflow:

# .github/workflows/update-deps.yml
