pip-licenses-cli

pip-licenses-cli

Dump the software license list of Python packages installed with pip.

Description

pip-licenses-cli is a CLI tool for checking the software licenses of installed Python packages with pip.

Implemented with the idea inspired by composer licenses command in Composer (a.k.a PHP package management tool): https://getcomposer.org/doc/03-cli.md#licenses

This is a fork of the original pip-licenses project. While pip-licenses-cli provides a CLI, pip-licenses-lib provides the library functionality. The CLI builds upon the library.

Installation

You can install this package from PyPI:

python -m pip install pip-licenses-cli

If you want to additionally parse license declarations with SPDX expressions, then also install the spdx extra:

python -m pip install 'pip-licenses-cli[spdx]'

Alternatively, you can use the package from source directly after installing the required dependencies.

Usage

Execute the command with your venv (or virtualenv) environment.

# Install packages in your venv environment
(venv) $ pip install Django pip-licenses-cli

# Check the licenses with your venv environment
(venv) $ pip-licenses
 Name    Version  License
 Django  2.0.2    BSD
 pytz    2017.3   MIT

For further details, see the detailed docs.

About UnicodeEncodeError

If a UnicodeEncodeError occurs, check your environment variables LANG and LC_TYPE. Additionally, you can set PYTHONIOENCODING to override the encoding used for stdout.

This mostly occurs in isolated environments such as Docker and tox.
