32位Linux系统是否支持PyQt5？如何获取该库？

Hey there, I’ve run into this exact issue before, so let’s break down the workarounds since Riverbank’s official docs state:

仅为Python v3.5及更高版本提供64位Linux、macOS以及32位和64位Windows的Wheels安装包

Here are the most reliable methods to get PyQt5 running on your 32-bit Linux setup:

• Compile from source
  This is the most universal approach, though it takes more time and resources. Here’s a quick walkthrough for Debian/Ubuntu-based distros:

  1. Install required dependencies first:

     sudo apt-get update && sudo apt-get install qt5-default python3-dev python3-pip build-essential
     

  2. Install SIP (a core dependency PyQt5 relies on):

     pip install sip
     

  3. Download the PyQt5 source code matching your Python version, extract it, then run these commands in the extracted folder:

     python configure.py
     make
     sudo make install
     

  Note: Compilation can take a while depending on your system’s specs, so make sure you have enough RAM and disk space available.

• Check your distro’s official repositories
  Many Linux distributions (especially older or specialized 32-bit ones) package PyQt5 for their 32-bit user base. For example, on Debian/Ubuntu, you can try:

  sudo apt-get install python3-pyqt5
  

  The version might not be the absolute latest, but it’ll be stable and pre-configured to work with your system.

• Try Conda (if supported)
  If you use Conda for package management, some community channels like conda-forge might host 32-bit Linux builds of PyQt5. Give this command a shot:

  conda install pyqt5 -c conda-forge
  

  Just keep in mind that support for 32-bit Linux in Conda has become limited in recent years, so this might not work for all distros.
