Dependency Checker

A lightweight pythonic way to verify if python packages are on the latest version

Install

pip install dependency-checker

How to use

from dependency_checker import get_installed_dependencies, is_latest_version

dependency_checker has two functionalities:

• Checking a python project's dependencies
• Checking if a python package is on the latest version

Each are intuitive to use, and have detailed documentation available.

To check a package's dependencies, we can use the get_installed_dependencies function, passing in the string name of the module:

get_installed_dependencies('dependency-checker', depth_limit=1)

{'packaging': '21.0', 'pip': '21.2.4', 'pipdeptree': '2.1.0'}

Generally a depth of 1 is enough to get a package's main dependencies, bar pip, packaging, and other "standard" python resources.

If we also want to include the original package, we can pass that in as a parameter:

get_installed_dependencies('dependency-checker', depth_limit=1, include_self=True)

{'dependency-checker': '0.0.1',
 'packaging': '21.0',
 'pip': '21.2.4',
 'pipdeptree': '2.1.0'}

There also exists is_latest_version, which will see if a package version is the latest available on pypi:

is_latest_version('pipdeptree', '2.0.9')

False

Automatically Building a requirements.txt file

You can also use dependency_checker to automatically build a requirements file from the command-line. It is an extension of pipreqs, combining both our functionalities together to give a more fine-grained and stable text file.
