nspektr is a distribution package dependency inspector.

It combines functionality from importlib.metadata and packaging to provide routines to resolve and validate dependencies for a package or entry point.

Highlights:

• resolve takes a requirement and returns a distribution satisfying that requirement (disregarding dependencies).
• find_dependencies takes a metadata.Distribution and generates all dependencies transitively as installed in the environment, avoiding loops.
• missing takes an entry point and identifies all unsatisfied dependencies for that entry point.
