Python Import Path Mismatch Debugging

When a ModuleNotFoundError occurs for an installed package, the issue is often an environment or path mismatch rather than a missing installation. Check: (1) which Python interpreter the CLI/script is using via which python or shebang lines, (2) confirm the package is installed in that specific environment with pip list, and (3) verify the active virtual environment matches where the package was installed. Use python -c "import module; print(module.__file__)" to trace which environment Python is actually loading from.
