Pip Tree

Get the dependency tree of your Python virtual environment via Pip.

There is no simple, native way to get the dependency tree of a Python virtual environment using the Pip package manager for Python. Pip Tree fixes this problem by retrieving every package from your virtual environment and returning a list of JSON objects that include the package name, version installed, date updated, and which packages are required by each package (the tree).

Install

# Install Pip Tree globally
pip3 install pip-tree

# Install Pip Tree into the virtual environment of the project you want to run it on
venv/bin/pip install pip-tree

# Install locally
just install

Usage

Virtual Env Usage:
    pip-tree

Global Usage:
    pip-tree --path "path/to/my_project/venv/lib/python3.9/site-packages"

Options:
    -h, --help            show this help message and exit
    -p PATH, --path PATH  The path to the site-packages directory of a Python virtual environment. If a path is not provided, the virtual environment Pip Tree is run from will be used.

Package

In addition to the CLI tool, you can use functions to retrieve the list of packages and their details from a Python virtual environment in your own code:

import pip_tree

path = 'path/to/my_project/venv/lib/python3.12/site-packages'

package_list = pip_tree.get_pip_package_list(path)
for package in package_list:
    package_details = pip_tree.get_package_details(package)
    print(package_details['name'])
