我如何解决这个问题我已经安装了微软c++构建工具，并尝试使用pyqt5车轮文件下载它(给我一个这个文件不是这个平台上支持的车轮

Answer 1

请尝试:

1. 下载文件PyQt5-5.15.4-cp36.cp37.cp38.cp39-none-win_amd64。WHL从页面https://pypi.org/project/PyQt5/文件

2. 重命名为PyQt5-5.15.4-py3-none-win_amd64.whl

3. 运行pip install PyQt5-5.15.4-py3-none-win_amd64.whl

我能够将它安装到Python 3.10虚拟环境中，然后能够从https://zetcode.com/gui/pyqt5/firstprograms/

运行示例。
