A utility to discover all package dependencies for a specific Python package

Project description

PackMap is a simple utility which finds all dependent packages for a given Python package. It does this by installing the package and all of its dependencies into a clean temporary virtual environment and probing installed components for their actual requirements.



PackMap is available on PyPI and can be installed with pip:
pip install packmap


Checking the dependencies of a package called lplight on PyPI:
packmap lplight –pdf-results
Checking the dependencies of a package on your hard drive:
packmap lplight –install-type path –install-path /path/to/package –pdf-results


PackMap output’s two different type of results; JSON and PDF.

  • JSON results: Gives you the ability to parse through the results for yourself to find changes in version numbers or requirement specs.
  • PDF results: Produces an graph for easier viewing and consumption.


The PDF results functionality requires the graphviz system package to be installed.
