PyQt5-sip

What it is and what it does

PyQt5-sip is the runtime support module for PyQt5, providing the `sip` module that underpins automatically generated extension code used to expose Qt5 classes, methods, and functions to Python. The package includes precompiled binary wheels for Python 3.10 through 3.14 on macOS, Linux, and Windows, eliminating the need to compile C++ code during installation on most platforms.

This package is part of the SIP ecosystem—a bindings generator originally created to build PyQt. While SIP itself is a code-generation tool that creates bindings specifications, PyQt5-sip is the compiled runtime component that makes those bindings work. Most users install it indirectly as a dependency of PyQt5 rather than directly.

Use it for:

• Install as a dependency when setting up PyQt5 for GUI development on Python 3.10 or later.
• Ensure compatible sip runtime when deploying PyQt5 applications across multiple Python versions.
• Verify sip module availability when debugging PyQt5 import errors.
• Support development environments where PyQt5 bindings must work with recent Python releases.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

PyQt5-sip provides the runtime support module for PyQt5 bindings, enabling Python code to call Qt5 C++ libraries through automatically generated extension modules.

Yes, if you are using PyQt5 on Python 3.10 or later. This package is typically installed automatically as a PyQt5 dependency, but direct installation may be needed for version pinning or troubleshooting. No known vulnerabilities, permissive license, and active maintenance make it safe.

Install

pyqt5-sip on PyPI

pip install pyqt5-sip

uv add pyqt5-sip

poetry add pyqt5-sip

Installing PyQt5-sip

Before you install

Prebuilt wheels are available for Python 3.10–3.14 across macOS, Linux, and Windows, reducing compile-time friction. The package is actively maintained with a recent release (12 days old) and no known vulnerabilities.

License in practice

Quickstart

pip install pyqt5-sip==12.19.0

import sip
# sip module is now available for PyQt5 bindings support

Requires Python 3.10 or later. This is a runtime support module; it is typically installed as a dependency of PyQt5 rather than directly.

Verify before relying

• Whether this package is intended for direct installation or primarily as an internal dependency of PyQt5.
• What specific functionality the sip module exposes beyond supporting PyQt5 extension modules.
• Whether prebuilt wheels cover all target platforms without requiring compilation.
