# PyQt5-Qt5 — The subset of a Qt installation needed by PyQt5.

License: copyleft · Maintenance: active · Downloads: 3.4M/mo

## What it is and what it does

PyQt5-Qt5 is a binary distribution package containing the Qt5 runtime libraries needed for PyQt5 to function. It is not typically installed directly; instead, it arrives automatically when you install PyQt5 via pip. The package bundles pre-compiled Qt5 libraries for multiple platforms (macOS Intel, macOS ARM64, and Linux x86_64), eliminating the need to build Qt5 from source or manage system Qt installations separately.

This package exists to simplify deployment by bundling Qt5 binaries in wheel format. It has no Python runtime dependencies and is maintained actively. Most users never interact with it directly—it arrives as a transitive dependency. The latest release was 2026-05-21.

Use it for:

- Automatic dependency resolution when installing for GUI development
- Cross-platform deployment without requiring system Qt5 libraries pre-installed
- Containerized or isolated Python environments where system Qt5 packages are unavailable
- Development on macOS with both Intel and ARM64 architecture support

## Worth the install?

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

Provides the Qt5 runtime libraries required by a PyQt5 installation, typically installed automatically as a dependency when you install PyQt5.

Yes, but only as a transitive dependency. Install the parent package normally and this will be pulled in automatically. Do not install directly unless you have a specific reason to manage Qt5 binaries separately. The LGPL v3 license requires compliance if you redistribute or modify; for typical use, this is not a concern.

## Install

pip install pyqt5-qt5
uv add pyqt5-qt5
poetry add pyqt5-qt5

## Installing PyQt5-Qt5

Before you install: Medium install friction due to platform-specific binary wheels (macOS x86_64, macOS ARM64, Linux x86_64 variants). Actively maintained with a release 85 days ago. Normally installed automatically as a dependency rather than directly.

License in practice: Licensed under LGPL v3 (copyleft). Derivative works and distributions must comply with copyleft obligations; review LGPL v3 terms if bundling or modifying.

Quickstart:

# Typically installed automatically:
# pip install PyQt5

# Direct installation (rarely needed):
# pip install PyQt5-Qt5==5.15.19

Platform-specific binary wheels; installation requires a compatible platform (macOS 10.13+, macOS 11.0 ARM64, or manylinux2014 x86_64).

Verify before relying:

- Whether this package can be installed standalone or only as a transitive dependency
- Python version compatibility beyond what wheel naming implies
- Whether direct installation is supported or recommended
