Known issues

breakingIn v0.3.0, the return type changed from dict to dataclass (Package). Attribute names were renamed to match PEP8. Code accessing dict keys or old attribute names will break.

fix

Upgrade to >=0.3.0 and use object attributes (e.g., pkg.name, pkg.version) instead of dictionary subscripting.

affects: <0.3.0

gotchaPackage model is not importable from the top-level; must import from pip_licenses_lib.models.Package. Doing from pip_licenses_lib import Package raises ImportError.

fix

Use from pip_licenses_lib.models import Package.

affects: >=0.3.0

deprecatedPython <=3.9 support dropped in v0.5.0; Python <=3.9 dropped again in v1.0.0 (now requires >=3.10).

fix

Upgrade Python to >=3.10 for latest version.

affects: <0.5.0, 0.5.0-0.6.0 require >=3.9, <1.0.0 requires >=3.9, >=1.0.0 requires >=3.10
