Installation¶

pkpdbib requires python >= 3.13 and is available from pypi. It is tested on Linux, macOS and Windows.

With uv¶

uv is the recommended way to install the package. In a project it is added as a dependency:

uv add pkpdbib

The scihub_pdfs command can also be used without installing the package into an environment:

uvx --from pkpdbib scihub_pdfs -j aliskiren.json

With pip¶

pip install pkpdbib

Dependencies¶

pkpdbib depends on rich for the console output, scidownl for the PDF retrieval, and pyzotero and polars for the Zotero libraries. It requires certifi>=2026.10.19, which requests (a dependency of scidownl) uses for its certificate authorities, so that no installation trusts the compromised emSign root CA of GHSA-6q48-6c7w-9gw2.

Development version¶

The current state of the develop branch is installed directly from GitHub:

uv add "pkpdbib @ git+https://github.com/matthiaskoenig/pkpdbib.git@develop"

or, with pip,

pip install git+https://github.com/matthiaskoenig/pkpdbib.git@develop

To work on the repository itself, with the test and documentation tooling, see Development.
