PyQt6-sip

13.11.1 · active · verified Thu Apr 09

PyQt6-sip provides the runtime 'sip' extension module necessary for the PyQt6 framework. SIP is a crucial tool developed by Riverbank Computing Limited for automatically generating Python bindings for C and C++ libraries, originally created for PyQt. The pyqt6-sip package specifically contains the compiled 'sip' module that PyQt6 uses internally. It is actively maintained with frequent releases, often synchronized with PyQt6 and new Python version support. The current version is 13.11.1.

Warnings

gotcha ModuleNotFoundError: No module named 'PyQt6.sip' errors are common. This often indicates an issue with the Python environment, virtual environment configuration, or incorrect installation paths where pyqt6-sip might be installed separately from other PyQt6 components.
Fix: Ensure `pyqt6-sip` is installed in the same Python environment as `PyQt6`. Try uninstalling and reinstalling `pyqt6-sip`. When using virtual environments, activate the environment before installing.
breaking PyQt6 6.7.1, when used with Python 3.13.0 (as of October 2024), experienced `ModuleNotFoundError: No module named 'PyQt6.sip'` errors. This points to potential compatibility issues with specific Python preview versions.
Fix: As a temporary workaround, consider using a stable Python version (e.g., Python 3.12 or earlier) or switching to PySide6 if you encounter this specific version incompatibility. Keep an eye on official PyQt6 and pyqt6-sip release notes for compatibility updates.
gotcha The `pyqt6-sip` package has a `Requires-Python` metadata that varies across its releases (e.g., >=3.7 for 13.5.0, >=3.8 for 13.8.0, >=3.10 for 13.11.1). Installing an incompatible version with your Python interpreter will lead to failures.
Fix: Always check the `Requires-Python` metadata on PyPI for the specific `pyqt6-sip` version you intend to install, or rely on `pip` to automatically select a compatible version for your Python environment.
breaking Version 13.9.0 of `pyqt6-sip` was yanked from PyPI due to an 'Incorrect Requires-Python' dependency specification, indicating a critical metadata error that could lead to installation issues or runtime problems.
Fix: Avoid installing `pyqt6-sip` version 13.9.0. Upgrade to a later stable release (e.g., 13.9.1 or newer).

Install

pip install pyqt6-sip Install with pip

Imports

sip
```
from PyQt6 import sip
```
Importing 'sip' directly refers to the standalone SIP binding generator tool, not the runtime module provided for PyQt6. The PyQt6-specific SIP module is found within the PyQt6 namespace.

Quickstart

While pyqt6-sip is primarily a backend component for PyQt6, you can verify its presence and retrieve its version information by importing 'sip' from the PyQt6 package.

from PyQt6 import sip

# Accessing a sip attribute to demonstrate the module is loaded
print(f"PyQt6.sip version string: {sip.SIP_VERSION_STR}")
print(f"PyQt6.sip API version: {sip.api_version}")
