# PyQt6-Qt6 — The subset of a Qt installation needed by PyQt6.

License: copyleft · Maintenance: active · Downloads: 2.7M/mo

## What it is and what it does

PyQt6-Qt6 is a binary distribution of the Qt6 framework libraries packaged as a Python wheel. It provides the compiled Qt runtime that dependent packages need to function, bundled in a way that pip can install directly without requiring users to compile Qt or install it separately on their system.

This is a support package with no public API. It is automatically pulled in when needed and should rarely require direct installation. The package is maintained by Riverbank Computing and tracks Qt6 releases, with platform-specific wheels for macOS (Intel and ARM), Linux (x86_64 and aarch64), and Windows (x86_64 and ARM).

Use it for:

- Automatic dependency resolution when installing packages that require Qt6 runtime.
- Ensuring consistent Qt6 runtime across different machines without system-level Qt installation.
- Building applications in CI/CD pipelines where system Qt packages may not be available.
- Cross-platform development where platform-specific Qt binaries are needed for each target OS.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides the Qt6 runtime libraries required by PyQt6, bundled as a wheel for direct installation without needing a separate Qt installation.

Yes, but only as a transitive dependency. Do not install directly unless pinning or updating its version independently. It is a support library with no public API and is meant to be managed automatically by dependent packages. The LGPL v3 copyleft license applies to any application using this package.

## Install

pip install pyqt6-qt6
uv add pyqt6-qt6
poetry add pyqt6-qt6

## Installing PyQt6-Qt6

Before you install: Medium install friction due to platform-specific wheels (macOS x86_64/arm64, Linux x86_64/aarch64, Windows amd64/arm64), but typically installed automatically as a transitive dependency.

License in practice: Licensed under LGPL v3 (copyleft). Applications using this package must comply with copyleft obligations: source code must be available and modifications disclosed under the same license terms.

Quickstart:

# Normally installed automatically
pip install PyQt6-Qt6==6.11.1

# Verify installation
import sys

Platform-specific wheel; installation requires a compatible platform (macOS 10.14+, Linux glibc 2.34+, or Windows).

Verify before relying:

- Whether this package can be used independently or only as a transitive dependency.
- Python version compatibility (requires_python is unspecified).
- Public API surface and direct usage patterns beyond automatic dependency resolution.
