【解决方案1】：

这是一个非常烦人的依赖问题，因为 cairocffi 不是为 windows 构建的，你需要额外的依赖，如那里所解释的：https://cairocffi.readthedocs.io/en/stable/overview.html#installing-cairo-on-windows

更快的解决方案是执行以下操作：我使用了从非官方存储库安装的 pipwin https://www.lfd.uci.edu/~gohlke/pythonlibs/#pycairo

pip install pipwin

pipwin install cairocffi

我开始使用其他东西，但我会检查是否在我的 Pyqt5 上使用它。泰
它仍然让我感到困惑，我开始使用 WPF for C# 进行设计。但是谢谢你的回答
