vamseeachanta Diagnose Virtual Environment Shebang Mismatch
When a CLI tool throws ModuleNotFoundError for an installed package, check if the entry point shebang (#!/usr/bin/env python3) resolves to a different Python than the venv where the package is installed. Verify the installed script location (which <command>) against the actual venv path. Update the shebang to explicitly point to the venv's Python binary (#!/path/to/venv/bin/python3). Note: reinstalls/updates may revert shebangs to generic defaults — check post-install hooks if this recurs.
