py-import-checker
A zero-dependency Python tool that scans a project and reports broken imports.
It loads Python files using the standard library and reports import failures before they reach runtime.
Features
- Zero dependencies (Python standard library only)
- Supports
src/layouts with--src - Reports
ImportErrorandModuleNotFoundError - Ignores runtime errors raised during module execution
- Skips virtual environments and build directories
- Works in CI with meaningful exit codes
- Auto-fix broken imports with
--fix(installs missing packages via pip) - Dry-run preview with
--dry-run(shows what would be installed, no side-effects)
Installation
pip install py-import-checker
Usage
py-import-checker
py-import-checker path/to/project
py-import-checker . --src src/
py-import-checker . --src src/ --src lib/
py-import-checker . --glob "app/**/*.py"
py-import-checker . --verbose
Auto-fix
Install every missing package detected during the scan:
py-import-checker . --fix
Preview what would be installed without touching the environment:
py-import-checker . --dry-run
After a successful --fix, the tool re-scans automatically to confirm all imports are resolved.
Python API
